摘要
A review on the technologies for GaAs high temperature electronic devices and integrated circuits is presented. Starting with high temperature related material properties of GaAs and related heterostructures, key issues for GaAs-based high temperature devices are identified and state of the art solutions are discussed. This includes for example high temperature stable metallizations, technologies for substrate leakage reduction and other topics. Based on these results the most important transistor technologies for high temperature applications (MESFETs, HFETs, HEMTs, JFETs and HBTs) are introduced and compared with each other The paper closes with a short review on analogue and microwave integrated circuits operating at high temperatures.
