  2. 11. Silicon dioxide and aluminium nitride as gate dielectric for high temperature and high power silicon carbide MOSFETs

    Author : Carl-Mikael Zetterling; KTH; []
    Keywords : ;

    Abstract : Silicon carbide (SIC) is a wide bandgap semiconductor thathas been suggested as a replacement for silicon in applicationsusing high voltages, high frequencies, high temperatures orcombinations thereof. Several basic process steps need to bedeveloped for reliable manufacturing of long-term stableelectronic devices. READ MORE

    Abstract : A process to achieve high inversion channel mobility in 4H-SiC MOSFETs is needed to enable manufacturing of devices for high power applications. In this thesis, investigations on the electrical properties of oxides produced in an alumina furnace are presented. READ MORE

  5. 13. Design and Fabrication of Silicon Carbide RF MOSFET for L- and S-band applications

    Author : Gudjon Gudjonsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Metal-Oxide-Semiconductor Field-Effect-Transistor MOSFET ; 4H-SiC; Silicon Carbide SiC ;

    Abstract : This thesis describes realisation of 4H-SiC radio-frequency metal-oxide-semiconductor field effect transistors (RF MOSFETs). Such transistors are in principle very attractive devices for high power and high frequency electronics. They are intended as a direct replacement for their silicon counterparts, offering higher power. READ MORE
