摘要

A thermal oxidation method with SrTi1-xMgxO3-delta used as an oxidation catalyst is proposed to oxidize the 4H-SiC surface at low temperatures. The rate constant for the interfacial reaction of the 4H-SiC(0001) Si-face at 800 degrees C is enhanced by approximately two orders of magnitude from that of conventional dry oxidation. The method enables the production of a gate SiO2 layer of a MOSFET at temperatures below 900 degrees C. Electrical characterization of the MOS interface suggests that the catalytic oxidation produces similar interface state densities to those produced by conventional dry oxidation in the energy range of 0.2-0.5 eV from the conduction band edge at 1300 degrees C.
