摘要：
We fabricated SiO2/4H-SiC (0001) MOS capacitors with nearly-ideal capacitance-voltage characteristics, simply by the control of thermal oxidation conditions which were selected based on thermodynamic and kinetic considerations of SiC oxidation. The interface with low interface defect state density <10(11) cm(-2)eV(-1) for the energy range 0.1 - 0.4 eV below the conduction band of SiC was obtained by thermal oxidation at 1300 degrees C in a ramp-heating furnace with a short rise/fall time, followed by low temperature O-2 anneal at 800 degrees C.
