IQE’s Infrared division presents invited papers at SPIE DCS

16 April 2018

Cardiff, UK, 16 April 2018: 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.  This year the company will be presenting a join paper with the University of Central Florida on InP based quantum cascade lasers (QCLs), this work reflecting IQE’s activity in the commercialisation of next generation mid-infrared lasers which have wide ranging mass market applications.  The company will also present an invited paper covering IQE’s development of cadmium zinc telluride substrates, an infrared material that is widely used in state-of-the-art infrared detectors.  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:

Monolithic integration of quantum cascade lasers onto a lattice-mismatched substrate

Invited paper 2:

Bulk characterization and surface analysis of epitaxy ready cadmium zinc telluride substrates for use in IRFPA manufacturing for IR imaging

SPIE DCS runs from 15 to 19 April at the Gaylord Palms Resort & Convention Center in Orlando, 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.
