In a method of fabricating a SiC semiconductor device, a surface of a SiC layer (5, 48, 102) is processed into a cleaned surface terminated at Si. An oxide film (7, 49, 105) is formed on the cleaned surface of the SiC layer. The SiC layer with the oxide film is subjected to thermal oxidation at a temperature in a range of 700° C. to 900° C. so that only terminal Si at the cleaned surface of the SiC layer is oxidated and an interface between the oxide film and the SiC layer becomes an SiO2/SiC cleaned interface.
