IQE plc is a leading global supplier of advanced wafer products and wafer-based material solutions for the semiconductor industry. Headquartered in Cardiff, Wales, the company specializes in the development and manufacturing of epitaxial wafers—ultra-thin layers of compound semiconductor materials—used in a wide range of high-performance electronic and photonic devices.
The company’s product portfolio encompasses key compound semiconductor materials such as indium phosphide, gallium arsenide, gallium nitride and silicon-germanium. These materials are critical to the manufacture of components for mobile communications (including 5G and emerging 6G technologies), optical fiber networks, light-emitting diodes (LEDs), lasers, high-power electronics, solar cells and sensors. IQE’s capabilities extend from research and prototyping through to high-volume production, supporting both fabless semiconductor firms and integrated device manufacturers.
Founded in 1988, IQE has grown through organic expansion and strategic acquisitions to establish manufacturing sites and R&D facilities across Europe, North America and Asia–Pacific—including locations in the United States, Taiwan, Singapore and China. The company serves a diverse customer base spanning telecommunications, aerospace and defense, data communications, consumer electronics and renewable energy. Under the leadership of Chief Executive Officer Dr. Drew Nelson, IQE continues to invest in next-generation epitaxial technologies to address the evolving requirements of the global semiconductor market.
