July 26, 2005 — IQE Inc., Bethlehem, PA, has begun shipping antimonide (Sb)-based epitaxial wafers, produced using the company’s molecular-beam epitaxy (MBE) platforms. Due to their unique bandgap and lattice properties, Sb-based materials are becoming attractive for high-frequency, low-noise, and low power-consumption electronic devices, as well as for long-wavelength emitters and detectors. IQE is planning to work with an expanding base of customers to further develop this market. Wafer Technology Ltd., another IQE group company, is already firmly established as a manufacturer of antimonide substrates (GaSb and InSb) on which advanced epitaxial layers can be produced.
