8 December 2010



Intel Corporation and IQE this week presented a joint paper on the development
of InGaAs Quantum Well Field Effect Transistors (QWFETs) for low power logic
applications. The paper was presented by Dr. Marko Radosavljevic from Intel
Corporation at the International Electron Devices Meeting (IEDM) held in San
Francisco, CA. The paper detailed work carried out by scientists at Intel's
Technology and Manufacturing Group in Oregon and IQE's epitaxial growth facility
in Bethlehem, Pennsylvania.
The paper, entitled: "Non-Planar, Multi-Gate InGaAs Quantum Well Field Effect
Transistors with High-K Gate Dielectric and Ultra-Scaled Gate-to-Drain/Gate-to-
Source Separation for Low Power Logic Applications," reports for the first time,
the results of work on InGaAs QWFETs with high-K gate dielectric and ultra-
scaled gate-to-drain and gate-to-source separations (L(SIDE)) of 5nm.

The QWFET devices fabricated by Intel using epitaxial wafers produced by IQE,
show improved enhancement-mode threshold voltage (V(T)) and significantly
improved electrostatics. The results of this work demonstrate that non-planar,
multi-gate device architecture is an effective way to improve the scalability of
III-V QWFETs for low power logic applications.

The IEDM has for almost sixty years been the world's main forum for reporting
breakthroughs in technology, design, manufacturing, physics and the modelling of
semiconductors and other electronic devices. Proceedings of the conference will
be published by the IEEE.

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, optical storage (CD, DVD), laser optical mouse, laser printers &
photocopiers, thermal imagers, leading-edge medical products, barcode, ultra
high brightness LEDs, a variety of advanced silicon based systems 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 comprises eight  operating 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.
