Abstract
High electron mobility transistors (HEMTs) are originally developed using GaAs-based compound semiconductor material systems and improved their high-frequency performance by using InP-based material systems. In this chapter, history and current status of HEMTs are reviewed. The contents include the operation principle of HEMTs, the characterization methodology, the process technologies, and the parasitic phenomena observed in HEMTs. Finally, the challenge and prospects for further improvements in high-frequency performance are discussed.
