SILICON CARBIDE SEMICONDUCTOR DEVICE MANUFACTURING METHOD

摘要

Disclosed is a manufacturing method of a SiC semiconductor device having improved performance. The disclosed manufacturing method of a SiC semiconductor device involves the following steps. A SiC semiconductor is prepared having a first surface at least one part of which is injected with impurities (S1-S3). A second surface is formed by cleaning the first surface of the Sic semiconductor (S4). A film containing Si is formed on the second surface (S5). By oxidizing the film containing Si, an oxide film is formed which configures the SiC semiconductor device (S6).
