Abstract

The development of silicon carbide complimentary metal-oxide-semiconductor (CMOS) is a key-enabling step in the realisation of low power circuitry for high-temperature applications. This paper describes investigations using the charge pumping technique into the properties of the gate dielectric interface as part of the development of the technology to realise monolithic fabrication of both n and p channel devices. A comparison of the charge pumping technique and the Hill-Coleman and Terman methods is also carried out to explore the feasibility of the technique.
