IQE plc develops, manufactures, and sells advanced semiconductor materials. The company operates in three segments: Wireless, Photonics, and CMOS++. It manufactures compound semiconductor wafers or epiwafers using epitaxy process; offers wireless products, including GaAs, GaN, and InP-based technologies, as well as Si and Ge-based epitaxial wafer structures; and supplies GaAs HBTs, pHEMTs, and BiFETs/BiHEMTs for use in consumer mobile handsets, connected devices, 5G network infrastructure, WiFi 6, Bluetooth, and satellite communications. The company also provides photonics products, which include vertical cavity surface emitting lasers, a 3D sensing technology that enables facial recognition, gesture control, light detection and ranging (LiDAR), and other advanced sensing applications; indium phosphide (InP) laser and detector wafers that powers high speed, 5G telecommunication, and data communication fiber optic networks; Gallium Nitride (GaN) and gallium arsenide (GaSb) for multicolor uLED displays; and a range of gallium antimonide (GaSb) and InP materials that enables high definition infrared imaging and sensing in security, health monitoring, and environmental applications. In addition, it offers substrate products, such as GaSb, InP, InAs, InSb, GaSb, CZT, custom size or geometry wafers, polycrystalline materials, high purity group iii/v source materials, and bespoke orientation substrates. Further, the company provides nanoimprint lithography services. The company serves in the United States, rest of the Americas, France, Germany, Israel, the United Kingdom, rest of Europe, the Middle East, Africa, the People's Republic of China, Japan, Taiwan, and rest of the Asia-Pacific. The company was founded in 1988 and is headquartered in Cardiff, the United Kingdom.
