The purchase orders are from three long term customers of IQEs Infrared Business Unit and are for various specifications of InSb and GaSb substrate materials, including large diameter products that are used to fabricate state-of-the art infrared detector products. InSb and GaSb are key materials for a wide range of infrared detector technologies in consumer, defence, security, medical and industrial imaging applications.

Further details of the specific customer, product and application cannot be disclosed at this time due to confidentiality designed to protect our customers IP and allow them to retain a competitive advantage.

IQE Infrared is uniquely positioned as a global market leader in the supply of antimonide materials to the IR detector industry, with IQEs US (Galaxy Compound Semiconductors) and UK (Wafer Technology) operations providing its customers with a secure dual source of 2-5 InSb and GaSb wafers. IQE has the Worlds largest antimonide wafer production capacity in the industry, using multiple production tools (pullers), volume double side polishing platforms and state-of-the art product metrology.

Dr. Mark J. Furlong, VP of IQEs Infrared Business Unit, commented:

'We are pleased to have received these new orders as they reflect the high quality of the antimonide substrate products that we supply as well as the confidence that our customers have in Galaxy Compound Semiconductors and Wafer Technology to support their longer term requirements for a wide range of InSb and GaSb substrate materials up to 5 in diameter.'
