Over £1M for global semiconductor firm IQE to enable industrialisation of ULTRARAM

An Innovate UK project worth £1.1M has been awarded to the Lancaster University spinout firm Quinas, the global semiconductor company IQE and Lancaster and Cardiff Universities. Quinas will coordinate the ambitious project which is the first step towards volume production of the universal computer memory ULTRARAM™ invented by Lancaster Physics Professor Manus Hayne. ULTRARAM has extraordinary properties, combining the non-volatility of a data storage memory, like flash, with the speed, energy-efficiency, and endurance of a working memory, like DRAM. Most of the funding for the one-year project will be spent at IQE which will scale up the manufacture of compound semiconductor layers from Lancaster University to an industrial process at the Cardiff based firm. This will involve IQE developing advanced capability for growth of the compound semiconductors gallium antimonide and aluminium antimonide for the first time. The project follows significant investment to boost the UK semiconductor industry and the establishment of the world’s first compound semiconductor cluster in South Wales. Professor Hayne, who is the Lancaster team lead, co-founder and Chief Scientific Officer at Quinas said: “We are delighted that Innovate UK is supporting this ambitious project, and that IQE has committed to developing the first part of ULTRARAM mass production.” It is estimated that the global memory chip market will be worth about US$320 billion by 2030 but the UK currently has no stake in it. Professor Hayne said: “ULTRARAM represents a tremendous economic opportunity for the UK, and the efficiencies it could bring to computing at all scales has the potential for huge energy savings and carbon emission reduction.” Jessica Wenmouth Lancaster University’s Head of Research Commercialisation said: “I am delighted to support our spinout Quinas on its journey to scale this Lancaster-led innovation to an industrial process suitable for a semiconductor foundry 'fab,’ thereby generating impact from research through commercialisation. “This project not only aligns with Lancaster University's strategy to foster impactful research and innovation but also demonstrates the effective utilisation of strategic grant funding alongside private equity investment. Such collaborations are crucial for bringing new products to market and driving significant investment into the UK for emerging technologies, enhancing our national and global standing in cutting-edge fields.” The goal of the one-year project to industrialise the process involves scaling up ULTRARAM wafer diameters from 3” at Lancaster to 6” at IQE. This will be achieved by using the mainstream production technique of metal-organic vapour phase epitaxy (MOVPE), also called metal-organic chemical vapour deposition (MOCVD), rather than molecular beam epitaxy (MBE), which is typically used at universities. Professor Hayne said: “Lancaster will do some initial MBE epitaxy as a control/template for the industrial growth. Our key role will be to characterise the antimonide material grown at IQE, and once sufficient quality is confirmed we will fabricate and test ULTRARAM memory on small areas of the wafers from IQE. “In parallel with this, Lancaster will continue to work on ULTRARAM scaling, by reducing the size of individual devices (‘Moore’s law’) and making larger and larger arrays. Once devices are small enough and arrays are large enough, the following stage will be to demonstrate fabrication on a complete 8” wafer, and then to translate the process to an industrial one, suitable for a semiconductor foundry ‘fab’.” ULTRARAM exploits quantum resonant tunnelling to achieve its extraordinary properties and is implemented in compound semiconductors that are used in photonic devices such as LEDs, laser diodes and infrared detectors, but not in digital electronics, which is the preserve of silicon.

Material and Manufacturing Improvements Enhance LED Efficiency

In theory, making high-brightness LEDs is easy. Just glue together n- and p-type semiconductors, add a small bias voltage, and stand back while the photons stream out. However, in practice these solid-state light sources are anything but simple. Advanced materials and manufacturing processes have come together to produce exotic devices with light outputs that would have been considered fanciful just half a decade ago.  Even though they produce impressive and highly efficient devices, the LED makers are not resting on their laurels. Leading LED companies such as Cree, OSRAM, and Seoul Semiconductor spend millions of dollars on material science and manufacturing technology to further enhance the performance of their products.  Contemporary high-brightness LEDs are already benefitting from advanced substrates and fabrication techniques, such as silicon carbide (SiC) and chemical vapor deposition (CVD), and tomorrow’s chips will take advantage of materials like patterned sapphire that are still percolating in the laboratory. This article takes a closer look at these materials and processes and assesses their impact on commercial LED performance.  Mind the band gap  Because the wavelength of the light emitted is a function of the energy band gap of the n- and p-doped semiconductor used to form the junction, engineers are limited in their choice of materials for fabricating LEDs. There is little point in selecting a semiconductor that emits photons that the eye cannot detect.  After many years of experimentation and hundreds of millions of research dollars, it turns out that Indium Gallium Nitride (InGaN) – a combination of Gallium Nitride (GaN) and Indium Nitride (InN) – is the best currently available semiconductor for high-brightness LEDs. The band gap of InGaN can be manipulated by altering the ratio of GaN to InN. The chips used at the heart of “white” LEDs, for example, emit photons in the 390 to 440 nanometer part of the spectrum (ultraviolet, violet-blue, and blue)1. These photons are then converted to white light by interaction with phosphor powder.  However, while InGaN has a number of advantages for photon generation, it does have some significant drawbacks from a volume manufacturing perspective. Chief among these is the fact that it is very difficult (and hence expensive) to “grow” InGaN ingots (unlike the silicon used for manufacturing integrated circuits (IC)). Ingots are advantageous for mass production because they can be sliced and processed as large wafers leading to lower cost chips.  Instead, manufacturers typically employ a much cheaper process whereby InGaN thin films are grown by a process known as epitaxy - the deposition of a crystalline overlayer on a crystalline substrate. There are several epitaxy techniques for forming the InGaN layer required for high-brightness LEDs, but the most common contemporary method is metal-organic CVD (MOCVD).  MOCVD is a complex process, but in basic terms, reactive gases are fed into a vacuum chamber and combine – at the atomic level – with the substrate and form a thin crystalline film.  During MOCVD, the crystalline structure of the deposited film attempts to orientate with the crystal structure of the substrate. The accuracy of this orientation depends on the similarity of the crystal lattice of each material. Poorly matched lattices result in a deposited film that while bulk crystalline on the macroscale is actually full of microscopic dislocations.  Reducing threading dislocations  A simplified schematic of the structure of a commercial high-brightness LED is shown in Figure 1.

The MOCVD process builds up the LED’s active regions – the multiple layers sandwiched between the p- and n-contact – by depositing successive thin films typically on a sapphire substrate. Sapphire has a number of advantages as a substrate for LED production: it is relatively inexpensive; it is used as a substrate for ICs so manufacturing processes are well established; it is very hard and durable, and it is a good insulator.  But there are some drawbacks. One such drawback is the mismatch in the coefficient of thermal expansion between sapphire and InGaN that can lead to high stresses and cracking of the fabricated die. However, an even bigger drawback is the relatively large mismatch between the crystal lattice of InGaN and sapphire (Figure 2). The mismatch – of around 14.8 percent – results in microscopic flaws in the InGaN thin film known as threading dislocations (Figure 3).

Figure 2: Lattice mismatch between sapphire substrate and InGaN thin film creates threading dislocations. (Courtesy of Cree.)

Figure 3: Threading dislocations in InGaN substrate.

Threading dislocations are a challenge in the drive to improve LED efficacy because recombinations between electrons and holes that occur at such sites are primarily “nonradiative.” In other words, no visible photon is emitted. This is because the dislocations introduce extra band gaps beyond the one that the designer intended, and hence do not correspond to the energy differential that produces a photon with a wavelength in the visible part of the spectrum.  Alternatively, the energy emitted in the recombination is transferred by the emission of a “phonon”, a vibration introduced to the crystal lattice that adds nothing to the chip’s luminosity but does generate unwanted heat. Because of the mismatch with the sapphire substrate, InGaN suffers from many threading dislocations, exhibiting typical densities exceeding 108 per cm2 or more.2 Worse yet, threading dislocations increase in number as the LED ages, further compromising luminosity (see the TechZone article “Understanding the Cause of Fading in High-Brightness LEDs”).  The drive for greater efficiency  Because of its fabrication advantages, the majority of manufacturers have been prepared to accept the threading dislocation compromise that comes with sapphire while improving their products’ efficacy by focusing on other aspects of LED performance.  LEDs such as OSRAM’s OSLON SSL, for example, can produce up to 108 lm/W (at 350 mA), a state-of-the-art performance, while fabricated on a sapphire substrate. In fact, over 90 percent of today’s high-brightness LEDs from most of the leading manufacturers are fabricated on sapphire substrates.3 As the efficacy returns from improving the other aspects of a LED’s performance – such as carrier injection efficiency, photon extraction, and phosphor conversion efficiency – begin to diminish, LED makers are turning their attention to alternative substrates.  One of those alternatives is silicon carbide (SiC). Like sapphire, SiC can be produced in bulk using fairly standard semiconductor manufacturing techniques. It also has the added advantage of a coefficient of thermal expansion that’s similar to InGaN, limiting stress buildup and die cracking. The primary disadvantages are high cost and patented manufacturing processes that require the payment of licensing fees.  Cree, a leading U.S.-based LED lighting maker, has – perhaps not surprisingly considering it owns many of the manufacturing patents – championed the use of SiC substrates for LED fabrication. The major advantage the material has over sapphire is a lattice structure that's much more closely matched to InGaN. By using SiC, the lattice mismatch with InGaN is reduced to 3.4 percent.4 This close matching is still not sufficient to eliminate threading defects completely (Figure 4), although the defect density is considerably reduced – by at least one and sometimes two orders of magnitude lower than sapphire5 – dramatically decreasing the number of sights for nonradiative recombination, improving efficacy and prolonging the life of the LED by slowing the rate of fading.

Transformation and upgrading direction of LED display industry

Email: sale05@xygledscreen.com

WhatsApp & Wechat: +86 18038197291

www.xygledscreen.com

In recent years, it can be seen from the products and businesses launched by screen enterprises that the entire industry has undergone a huge change: LED screen enterprises have changed from simple manufacturing and sales to comprehensive products. Such as smart all-in-one machine and other consumer market products that adapt to more commercial display scenes, command and scheduling solutions that are suitable for the construction of special display scenes, and application cases of "product+content production/creative design" in cultural and entertainment scenes. It can be seen that the tentacles of LED display industry have been extended outward.

The saturated professional market has given birth to new development needs

Throughout the development history of LED display, it is only 30 years. Before the 1990s, China's LED display industry was still in its infancy, and the products were mainly monochrome and red-green LED display products. After the 1990s, LED display entered the full-color period, and the LED display industry also ushered in a period of rapid development. The application field is gradually expanded and the industrial pattern is gradually improved. Especially after 2008, LED display screen has entered a new stage of development in terms of design concept, technical innovation, project scale, display effect, etc. In this process, there are also inevitable problems: the industry competition intensifies, and in order to seize the market, screen companies compete in price war. The quality of products on the market is also mixed, which also promotes the further implementation of industry norms and guidance. With the increase of production capacity and expansion of scale, the intensive development effect of the industry has become increasingly obvious. After more than 30 years of development, China's LED industry has formed a relatively complete industrial chain, including the production of epitaxial wafers, chip preparation and packaging, and the application of LED products.

For a long time, the development of LED display screen industry has been based on market demand, and technical research and development have been carried out on the display effect of products. The application field also has obvious characteristics: focusing on large-screen display, and focusing on the demand for information video display. With the increase of market demand, screen enterprises also continue to expand application scenarios and develop display application products in advertising media, transportation, sports, education, security and other markets. However, with the gradual saturation of the professional market, after a long period of market competition, the intensive trend of the screen enterprises is obvious, and the screen enterprises either integrate and merge, or create another market segment. After experiencing a series of internal and external factors transformation, in the gradually mature and saturated market, the competition between screen enterprises has become increasingly fierce, and gradually began to be unable to meet the needs of screen enterprises for further improvement and development. The development of the LED display industry is very similar to that of the large LCD screen market. At present, only a few leading enterprises in the LCD market are in a stagnant state of development in the quantitative share market, which also sounded a warning bell for the LED display market: when the traditional professional market has entered a saturation state, and the research and development of LED screen enterprises in the traditional product display technology can no longer rise, where should the screen enterprises go?

Try and adjust

In fact, from the development trend of LED display industry in recent years, we can see that screen enterprises are making new attempts and adjustments.

The shallowest attempt should be to transform module products into complete machine products and enter the commercial display market. In this attempt, the screen enterprise changed the original LED display screen from the video processor into the processor and display screen integrated into one product, and output the small spacing all-in-one machine product suitable for indoor use to the indoor display scene. This also means that LED display will not only compete with all kinds of splicing display products in the large screen market, but also compete for indoor display space in the field of commercial display, medium and large size display. LED screen enterprises follow a principle in product upgrading: how to make LED screen operation more convenient and convenient?

Perhaps inspired by information technology and digital products in recent years, combined with the development of 5G and other information technologies in recent years, the large display screen is no longer simply used as a display board of video materials, but the all-in-one machine products with software functions have been applied to various conference rooms, security monitoring, education fields and other places, and there are corresponding functional focus for the place, and even the product has achieved multi-function features, which can meet the needs of various application scenarios. Recently, LED all-in-one products are also emerging in an endless stream at major technology exhibitions. For large screen application scenarios such as the command center, various large screen enterprises have launched various integrated solutions. Thanks to the rising demand for digital upgrading of various scenes under the construction of smart cities, LED displays are given more market opportunities and market space. In fact, the smart all-in-one machine and the integrated solutions launched by various screen enterprises can also be regarded as an intelligent upgrade of screen products by screen enterprises, combining individual module discrete parts into a whole product, and matching the appropriate display operation software for consumer groups. This kind of product well meets the consumer's demand for simplified operation requirements of LED display, and becomes another competitive advantage of LED display products.

At the same time, screen enterprises also try to improve the added value of products and market competitiveness by "empowering" display products. In the market situation where the traditional LED display technology is maturing and the industry competition is becoming increasingly fierce, many screen enterprises have developed new business points in the application field, and "product+content production/creative design" has become the company's new business model. Relying on technological innovation, the product types of LED display are more diverse, and the combination with art design is more close, which creates more application space for the industry, but also challenges the display content of LED display with different appearances. This year, the trend of screen enterprises to layout the digital content sector is obvious. Many screen enterprises have developed digital content scene building businesses, including XR virtual digital people, virtual venues, virtual live broadcasting, bare-eye 3D and other digital content services. It also provides digital content design and production for the combination of various special-shaped displays and modern decoration, landscape and lighting in the bar, stage, art exhibition hall and other application scenarios to create more beautiful creative display application cases. LED display enterprises located in the professional field obviously know more about product characteristics, which also provides convenience for display enterprises to enter the digital content production market.

The evolution of the market and products has pushed the distance between screen enterprises and consumers closer. The market demand for LED display products has changed from rigid video information display to more flexible and unknown. With the development of Internet information technology, information dissemination is becoming more and more developed, LED display screens are no longer half understood by consumers, and the requirements for LED display products will be more stringent. However, the original market has become too saturated and the competition is fierce. In order to open up new markets and take the lead, enterprises must open up new LED display application roads, learn more "skills" and increase the "attribute value" of products.

Researchers Create First Functional Semiconductor Made From Graphene

Researchers at the Georgia Institute of Technology have created the world’s first functional semiconductor made from graphene, a single sheet of carbon atoms held together by the strongest bonds known. Semiconductors, which are materials that conduct electricity under specific conditions, are foundational components of electronic devices. The team’s breakthrough throws open the door to a new way of doing electronics. Their discovery comes at a time when silicon, the material from which nearly all modern electronics are made, is reaching its limit in the face of increasingly faster computing and smaller electronic devices. Walter de Heer, Regents’ Professor of physics at Georgia Tech, led a team of researchers based in Atlanta, Georgia, and Tianjin, China, to produce a graphene semiconductor that is compatible with conventional microelectronics processing methods — a necessity for any viable alternative to silicon. https://youtu.be/gWUX2OTqkEo In this latest research, published in Nature, de Heer and his team overcame the paramount hurdle that has been plaguing graphene research for decades, and the reason why many thought graphene electronics would never work. Known as the "band gap", it is a crucial electronic property that allows semiconductors to switch on and off. Graphene didn't have a band gap – until now.  De Heer started to explore carbon-based materials as potential semiconductors early in his career, and then made the switch to 2D graphene in 2001. He knew at that time that graphene had potential for electronics. "We were motivated by the hope of introducing three special properties of graphene into electronics," he said. "It's an extremely robust material, one that can handle very large currents, and can do so without heating up and falling apart." De Heer achieved a breakthrough when he and his team figured out how to grow graphene on silicon carbide wafers using special furnaces. They produced epitaxial graphene, which is a single layer that grows on a crystal face of the silicon carbide. The team found that when it was made properly, the epitaxial graphene chemically bonded to the silicon carbide and started to show semiconducting properties. Over the next decade, they persisted in perfecting the material at Georgia Tech and later in collaboration with colleagues at the Tianjin International Center for Nanoparticles and Nanosystems at Tianjin University in China. De Heer founded the center in 2014 with Lei Ma, the center’s director and a co-author of the paper. How They Did It In its natural form, graphene is neither a semiconductor nor a metal, but a semimetal. A band gap is a material that can be turned on and off when an electric field is applied to it, which is how all transistors and silicon electronics work. The major question in graphene electronics research was how to switch it on and off so it can work like silicon. But to make a functional transistor, a semiconducting material must be greatly manipulated, which can damage its properties. To prove that their platform could function as a viable semiconductor, the team needed to measure its electronic properties without damaging it. They put atoms on the graphene that "donate" electrons to the system — a technique called doping, used to see whether the material was a good conductor. It worked without damaging the material or its properties.  The team's measurements showed that their graphene semiconductor has 10 times greater mobility than silicon. In other words, the electrons move with very low resistance, which, in electronics, translates to faster computing. "It's like driving on a gravel road versus driving on a freeway," de Heer said. "It's more efficient, it doesn't heat up as much, and it allows for higher speeds so that the electrons can move faster." The team’s product is currently the only two-dimensional semiconductor that has all the necessary properties to be used in nanoelectronics, and its electrical properties are far superior to any other 2D semiconductors currently in development.  Epitaxial graphene could cause a paradigm shift in the field of electronics and allow for completely new technologies that take advantage of its unique properties. The material allows the quantum mechanical wave properties of electrons to be utilized, which is a requirement for quantum computing. "Our motivation for doing graphene electronics has been there for a long time, and the rest was just making it happen," de Heer said. "We had to learn how to treat the material, how to make it better and better, and finally how to measure the properties. That took a very, very long time." According to de Heer, it is not unusual to see yet another generation of electronics on its way. Before silicon, there were vacuum tubes, and before that, there were wires and telegraphs. Silicon is one of many steps in the history of electronics, and the next step could be graphene. "To me, this is like a Wright brothers moment," de Heer said. "They built a plane that could fly 300 feet through the air. But the skeptics asked why the world would need flight when it already had fast trains and boats. But they persisted, and it was the beginning of a technology that can take people across oceans." Story via - The Georgia Institute of Technology Read the full article

Virtual and augmented reality: Researchers pioneer process to stack micro-LEDs

Now, researchers from the Georgia Institute of Technology, in collaboration with researchers from the Massachusetts Institute of Technology (MIT), have developed a new process based on 2D materials to create LED displays with smaller and thinner pixels. Enabled by two-dimensional, materials-based layer transfer technology, the innovation promises a future of clearer and more realistic LED displays. The team published a paper in the journal Nature in February titled, “Vertical full-colour micro-LEDs via 2D materials-based layer transfer.” Co-authors also include researchers from Sejong University in Korea, and from additional institutions in the U.S. and South Korea. Georgia Tech-Europe Professor Abdallah Ougazzaden and research scientist Suresh Sundaram (who both also hold appointments in Georgia Tech’s School of Electrical and Computer Engineering) collaborated with researchers from MIT to turn the conventional LED manufacturing process on its head — literally. Instead of using prevailing processes based on laying red, green, and blue (RGB) LEDs side by side, which limits pixel density, the team vertically stacked freestanding, ultrathin RGB LED membranes, achieving an array density of 5,100 pixels per inch — the smallest pixel size reported to date (4 microns) and the smallest-ever stack height — all while delivering a full commercial range of colors. This ultra-small vertical stack was achieved via the technology of van der Waals epitaxy on 2D boron nitride developed at the Georgia Tech-Europe lab and the technology of remote epitaxy on graphene developed at MIT. The study showed that the world’s thinnest and smallest pixeled displays can be enabled by an active layer separation technology using 2D materials such as graphene and boron to enable high array density micro-LEDs resulting in full-color realization of micro-LED displays. One unique facet of the two-dimensional, material-based layer transfer (2DLT) technique is that it allows the reuse of epitaxial wafers. Reusing this costly substrate could significantly lower the cost for manufacturing smaller, thinner, and more realistic displays. “We have now demonstrated that this advanced 2D, materials-based growth and transfer technology can surpass conventional growth and transfer technology in specific domains, such as in virtual and augmented reality displays,” said Ougazzaden, the lead researcher for the Georgia Tech team. These advanced techniques were developed in metalorganic chemical vapor deposition (MOCVD) reactors, the key tool for LED production at the wafer scale. The 2DLT technique can be replicated on an industrial scale with high throughput yield. The technology has the potential to bring the field of virtual and augmented reality to the next level, enabling the next generation of immersive, realistic micro-LED displays. “This emerging technology has a tremendous potential for flexible electronics and the heterogenous integration in opto-electronics, which we believe will develop new functionalities and attract industry to develop commercial products from smartphone screens to medical devices,” Ougazzaden said.
