IQE plc specializes in the development, production, and sale of sophisticated semiconductor materials. The company's operations are divided into three main divisions: Wireless, Photonics, and CMOS++. It manufactures compound semiconductor wafers, known as epiwafers, utilizing an epitaxy process. Within its Wireless segment, IQE offers various products based on Gallium Arsenide (GaAs), Gallium Nitride (GaN), and Indium Phosphide (InP) technologies, alongside silicon and germanium epitaxial wafer structures. These include GaAs HBTs, pHEMTs, and BiFETs/BiHEMTs, which are crucial components for applications such as mobile phones, smart devices, 5G infrastructure, WiFi 6, Bluetooth, and satellite communication systems. The Photonics division provides innovative solutions like vertical cavity surface emitting lasers (VCSELs). These VCSELs enable advanced 3D sensing functionalities, including facial recognition, gesture control, and light detection and ranging (LiDAR), as well as other sensing applications. The company also supplies Indium Phosphide (InP) laser and detector wafers, essential for high-speed 5G telecommunications and fiber optic data networks. Furthermore, IQE offers Gallium Nitride (GaN) and Gallium Antimonide (GaSb) for multicolor micro-LED displays, and a range of GaSb and InP materials used in high-definition infrared imaging and sensing for security, health monitoring, and environmental monitoring. Beyond these, IQE manufactures a variety of substrate products, including GaSb, InP, InAs, InSb, CZT, along with custom-sized or geometric wafers, polycrystalline materials, high-purity group III/V source materials, and tailor-made orientation substrates. The company also offers specialized services such as nanoimprint lithography. IQE plc operates globally, serving customers across the United States, the wider Americas, France, Germany, Israel, the United Kingdom, the rest of Europe, the Middle East, Africa, the People's Republic of China, Japan, Taiwan, and the broader Asia-Pacific region. Established in 1988, IQE plc maintains its headquarters in Cardiff, United Kingdom.
