ION IMPLANTATION IN III–V SEMICONDUCTOR TECHNOLOGY

A review is given of the applications of ion implantation in III–V compound semiconductor device technology, beginning with the fundamentals of ion stopping in these materials and describing the use of implantation for both doping and isolation. There is increasing interest in the use of MeV implantation to create unique doping profiles or for the isolation of thick device structures such as heterojunction bipolar transistors or multi quantum well lasers, and we give details of these areas and the metal masking layers necessary for selective area processing. Finally, examples are given of the use of implantation in a variety of III–V devices.
