IQE’s Infrared division presents invited papers at SPIE DCS

19 April 2016

Cardiff, UK, 19 April 2016: IQE plc (AIM: IQE; "IQE", the "Group"), the leading global supplier of advanced semiconductor wafer products and services to the semiconductor industry, will present two invited 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 and this year has been invited to present two papers based on developments and commercialisation of advanced infrared materials.

Invited paper 1:

Bulk Growth and Surface Characterization of Epitaxy Ready Cadmium Zinc Telluride substrates for use in IR imaging applications.

Covering new product development in the area of cadmium zinc telluride (CZT) IR substrate technology through a partnership between IQE’s US substrate manufacturing subsidiary, Galaxy Compound Semiconductors and Redlen Technologies of Victoria, BC, Canada ( a leader in the manufacture of CZT based radiation detectors.


Invited paper 2:

A study of the preparation of epitaxy-ready polished surfaces of (100) Gallium Antimonide substrates demonstrating ultra-low surface defects for MBE growth.


SPIE DCS runs from 17 to 21 April at the Convention Center in Baltimore, 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.
