Abstract :
A technological concept for a InP-HFET structure fully grown and processed at a low temperature of 280°C is presented. It is based on low temperature grown (LTG) InP used as a auto-doped channel material and LTG-AlInAs as buffer and Schottky layer. Design and optimization, especially the transition from the P containing to the As containing compounds of the Schottky gate heterostructure contact layer is discussed. The proof of concept is demonstrated with a first FET device
