IQE’s Infrared division presents invited papers at SPIE DCS

10 April 2017

Cardiff, UK, 10 April 2017: IQE plc (AIM: IQE; "IQE", the "Group"), the leading global supplier of advanced semiconductor wafer products and services to the semiconductor industry, will present papers on recent key developments in advanced infrared technologies at SPIE Defense and Commercial Sensing conference (DCS).

IQE’s Infrared business unit has established a strong presence at SPIE DCS with the presentation of a number of papers based on developments and commercialisation of advanced infrared materials.  Complementing papers demonstrating the development of large diameter antimonide substrates will be two presentations covering IQE’s five-year contribution to the Vital Infrared Sensor Technology Acceleration (VISTA) program, from which an industry-leading range of GaSb substrate and epitaxial material technologies has been developed.  Furthermore, IQE’s infrared materials portfolio has been now been expanded further by the addition of another industry critical infrared material, cadmium zinc telluride (CZT), our paper describing the development of this material through to commercialization.  Collectively these developments enable IQE to offer an industry leading range of infrared materials, providing full spectrum coverage across a wide and diverse range of detector and sensing applications.

Invited paper 1:

Production manufacturing of 5” diameter gallium antimonide substrates

Invited paper 2:

MBE growth of advanced Sb-based IR photodetector structures for the VISTA Program

Invited paper 3:

Bulk growth and surface characterization of epitaxy ready cadmium zinc telluride substrates for use in IR imaging applications

Invited paper 4:

Large-format multi-wafer production of 5” GaSb-based photodetectors by molecular beam epitaxy

Invited paper 5:

Standardizing large format 5” GaSb and InSb substrate production

SPIE DCS runs from 09 to 13 April at the Convention Center in Anaheim, USA and is expected to attract around 5,000 visitors.

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 smartphones and wireless infrastructure, Wi-Fi, base stations, GPS, and satellite communications; optical communications, optical storage, printing, 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 operates multiple manufacturing and R&D facilities facilities worldwide.
