Research on the growth of gallium nitride (GaN) light-emitting diode (LED) structures has led to the creation of two spin-out businesses (subsequently sold), has assisted Forge Europa Ltd in expanding its sales of LED-lighting products, has helped AIXTRON to achieve sales of related GaN-growth equipment [text removed for publication], & has enabled Plessey Semiconductors Ltd to manufacture the world's first commercially available LEDs on 6-inch Si (& the first LEDs to be manufactured in the UK).
Research on vapour growth of semiconductor compounds led to a key breakthrough in growing large crystals which form the basis for sensitive X-and gamma-ray detectors. The process was commercialised by a Durham University spin-out company, Kromek Ltd., which floated on AIM at £55M and has over 100 employees in the UK and USA. The X-ray detectors are in use in Kromek's security systems for screening liquids at airports, significantly reducing restrictions on duty free goods. This application won the $400,000 international prize in the 2009 Global Security Challenge. The company also markets gamma-ray detectors for nuclear isotope identification. These have won contracts totalling $7.5M from the US Defense Threat Reduction Agency and are in use at Fukushima.
This University of Manchester research underpins UK industry's global position in millimetre- wave imaging and ultra-high-precision sensing. These are key technologies in a range of industrial, medical and consumer electronics applications. The devices and methods developed by the research team are now used by a range of companies leading to economic impacts for the UK in strong export markets. In this case study we provide examples of impacts that support commercial sales in excess of £300m by UK SME and FTSE-listed companies in three sectors: automotive radar (e2v), terahertz imaging (TeraView), and linear encoders (Renishaw PLC).
Raman thermography, a new technique for measuring channel temperature in semiconductor electronic devices developed at the University of Bristol, has been used by many companies to characterise their semiconductor devices. The technology has enabled companies to develop more robust, reliable, higher performing devices and circuits for high-end space, radar, communication and power conversion applications. This is illustrated here in detail on the example of the company, United Monolithic Semiconductor (UMS) (Germany-France), which used the technique to improve the lifetime of its Gallium Nitride (GaN) and Gallium Arsenide (GaAs) semiconductor devices so that they meet customer requirements for product qualification. Corresponding impact resulted for the companies TriQuint (USA), Northrup Grumman (USA), QinetiQ (UK), Selex Galileo (UK & Italy), NXP (UK & Netherlands), Thales Alenia Spaciale (France), Sharp (Japan) and Hitachi Cable (Japan).
The commercialisation of Quantum Cascade Lasers (QCL) and the associated novel fabrication processes developed at the University of Glasgow has provided Compound Semiconductor Technologies Global Ltd (CSTG) with a new foundry product supplying quantum cascade lasers for gas sensing, safety and security, and military applications. This resulted in 40% turnover growth from 2010-2012 and the company is now recognised as a global leader in QCLs and their fabrication. Based on University of Glasgow research, the company has created a manufacturing toolbox for the production of a wide variety of QCL chip designs. CSTG has also achieved a world first, manufacturing QCLs for systems that detect explosives at a safe distance and can counter heat-seeking missile attacks on aircraft.
Research (1993-2008) on novel silicon architectures and design methodologies for digital signal and video processing led to the creation of world leading semiconductor IP cores (chip designs) for implementing the main video and image compression standards including H.264, MPEG4, MPEG2, and JPEG2000. These have been licensed to semiconductor manufacturers worldwide including Panasonic, Sony, Toshiba and Sharp. Since 2008, such encoders/decoders have been incorporated into all DTV/HDTV SoCs produced by Conexant, NXP, Trident Microsystems and Entropic. They have also been used as the hardware acceleration engines in Intel's C2110 Media Processor. At least 150 million chips worldwide having been manufactured incorporating this technology.
The development of microelectronic sensor arrays for biological applications, pioneered at the University of Glasgow, is central to a unique gene sequencing system developed by Ion Torrent. The Ion Torrent personal genome machine is a bench-top system that, compared to optically mediated technologies, is cheaper and easier to use. Ion Torrent was founded in 2007 and bought by Life Technologies in 2010 for $725M; they, in turn, were bought by Thermo Fisher for $13Bn, citing Ion Torrent as a motivation. Ion Torrent now has 62% of the bench-top sequencing market, estimated to be worth $1.3Bn in 2012.
Researchers within the Department of Physics and Astronomy at UCL have investigated the properties of defects in bulk HfO2 and at Si/SiOx/HfO2 interfaces. Results have been used by an industrial partner, SEMATECH (SMT), to improve the quality and reliability of high-performance microelectronic devices based on transistors. This has helped SMT to meet project objectives on behalf of member companies such as Intel and IBM, and UCL research results have been consistently highly evaluated by these companies. Recommendations made by SMT have been implemented by industrial partners in their currently manufactured devices, such as the 22nm process technology released by Intel in 2011.
Research on high-voltage power devices by the University of Cambridge Department of Engineering (DoEng) was commercialised by its spin-off company, Cambridge Semiconductor Limited (CamSemi), which, in the REF period, has:
CamSemi chips are more efficient than traditional linear power supplies. The CamSemi chips that were produced before the end of the REF period are estimated to save of the order of 100GWh of electricity and 50,000 tonnes of CO2 emissions per year in total.
The underpinning research involved modelling the diffusion of hydrogen on silicon surfaces, and the electronic structure of dopant atoms on silicon surfaces. This data was used to inform, guide and develop the atomically precise manufacturing processes of Zyvex Labs. These processes remove hydrogen atoms from a silicon surface to create patterns with atomic precision for later overgrowth. As a result of the UCL research, Zyvex Labs has already obtained funding of $14 million, several jobs have been created, and at least two products are being brought to market.
