IQE presents five invited papers at Photonics West in San Francisco
Cardiff, UK, 18 Cardiff, 25 January 2012 - IQE plc (AIM: IQE), the leading global supplier of advanced semiconductor wafer products and services to the semiconductor industry, this week presented a series of invited papers on recent key developments in advanced photonic technologies at the world’s premier optoelectronics event, Photonics West.
The IQE Group established a strong presence at Photonics West with the presentation of a number of invited papers based on developments and commercialisation of advanced infrared materials:
1) Manufacturable MBE Growth Process for Sb-based Photodetector Materials on Large Diameter Substrates" (Joint paper with ASL, Analytical).
2) Manufacturing of 100mm diameter GaSb substrates for advanced space based applications (joint paper with Jet Propulsion Labs, USA)
3) Multiwafer production of epitaxy ready 4” GaSb substrates: requirements for epitaxially grown infrared detectors
4) Surface chemistry improvement of 100mm GaSb for advanced space based applications.
5) Study of the valence band offsets between InAs and InAs1-xSbx alloys (joint paper with Arizona State University).
Photonics West runs from 24 to 26 January at the Moscone Convention Center in San Francisco and is expected to attract around 1,100 exhibitors and 19,000 visitors.

Note to Editors
IQE is the leading global supplier of advanced semiconductor wafers with products that cover a diverse range of applications, supported by an innovative outsourced foundry services portfolio that allows the Group to provide a 'one stop shop' for the wafer needs of the world's leading semiconductor manufacturers.
IQE uses advanced crystal growth technology (epitaxy) to manufacture and supply bespoke semiconductor wafers ('epi-wafers') to the major chip manufacturing companies, who then use these wafers to make the chips which form the key components of virtually all high technology systems. IQE is unique in being able to supply wafers using all of the leading crystal growth technology platforms.
IQE's products are found in many leading-edge consumer, communication, computing and industrial applications, including a complete range of wafer products for the wireless industry, such as mobile handsets and wireless infrastructure, Wi-Fi, WiMAX, base stations, GPS, and satellite communications; optical communications. The Group also manufactures advanced optoelectronic and photonic components such as semiconductor lasers, vertical cavity surface emitting lasers (VCSELs) and optical sensors for a wide range of applications including optical storage (CD, DVD, BluRay), thermal imaging, leading-edge medical products, pico-projection, finger navigation ultra high brightness LEDs, and high efficiency concentrator photovoltaic (CPV) solar cells.
The manufacturers of these chips are increasingly seeking to outsource wafer production to specialist foundries such as IQE in order to reduce overall wafer costs and accelerate time to market.
IQE also provides bespoke R&D services to deliver customised materials for specific applications and offers specialist technical staff to manufacture to specification either at its own facilities or on the customer's own sites. The Group is also able to leverage its global purchasing volumes to reduce the cost of raw materials. In this way, IQE's outsourced services, provide compelling benefits in terms of flexibility and predictability of cost, thereby significantly reducing operating risk.
IQE operates eight facilities located in Cardiff (two), Milton Keynes and Bath in the UK; in Bethlehem, Pennsylvania, Somerset, New Jersey and Spokane, Washington in the USA; and Singapore. The Group also has 11 sales offices located in major economic centres worldwide.
