Abstract:
1. A method of manufacturing a silicon carbide semiconductor device, comprising the steps of: (a) forming an active region of a silicon carbide semiconductor device by ion-implanting an impurity in a surface of a silicon carbide wafer; (b) forming a graphite film on an entire surface of said silicon carbide wafer which is obtained after said active region is formed and an entire surface of a silicon wafer which is used as a film thickness monitor, by a chemical vapor deposition; and (c) evaluating the thickness of said graphite film, wherein said step (b) includes the step of forming said graphite film at a film-forming temperature of 950° C. or lower by said chemical vapor deposition, said step (c) includes the step of estimating the thickness of said graphite film formed on said silicon carbide wafer by measuring the thickness of said graphite film formed on said silicon wafer.
