SOI power devices

This paper provides an introduction to silicon-on-insulator (SOI) technolog y and the operating principles of high-voltage SOI devices, reviews the per formance of the available SOI switching devices in comparison with standard silicon devices, discusses the reasoning behind the use of SOI technology in power applications and briefly covers the most advanced novel power SOI devices proposed to date. The impact of SOI technology in power integrated circuits (PICs) and the problems associated with the integration of high-vo ltage and low-voltage CMOS are also briefly analysed.
