IQE's Wafer Technology division launches new 4" product range

04 February 2010

Milton Keynes, UK. February 2010: IQE plc (AIM: IQE, “IQE” or the “Group”), the leading global supplier of advanced semiconductor wafer products and wafer services to the semiconductor industry, is pleased to announce that its UK based wafer operation, Wafer Technology Ltd., is to extend its gallium antimonide (GaSb) product range to include 4” diameter wafers.
GaSb materials are used in the manufacture of a wide range of products including infrared laser diodes, detectors and thermophotovoltaic (TPV) cells that can convert infrared (heat) energy into electrical power.
4” GaSb-Te wafers are now available and can be specified in the same way as for existing 2” and 3” GaSb products. High accuracy orientations (+/-0.1 deg.) and proprietary epitaxy ready finishes are offered to ensure consistent performance in epitaxial growth. Whole 4” wafer etch pit density (EPD) maps (69 points) are supplied to support yield maximisation in the manufacture of large area detector arrays.
The new product offering will be produced at the Group’s Wafer Technology facility in Milton Keynes, UK.
Dr. Mark J. Furlong, General Manager at Wafer Technology, commented:
“Delivering 4” GaSb product is an important milestone for Wafer Technology, especially at a time when the industry is looking to produce larger area epitaxially grown arrays.
“Our 4” GaSb wafers have been very well received by our first customers qualifying this product, so we are looking forward to satisfying new demands for large area GaSb wafers in 2010.”
