Abstract(in English) | In the EC etching, only p-type SiC is selectively etched through the following mechanism. SiC is oxidized by holes supplied from p-type SiC to the SiC/electrolyte interface. Subsequently, the formed oxide (SiOx) is removed (chemically etched) by the electrolyte. The EC etching suffers from formation of etch pits at the places where dislocations intersect the surface. In this study, we found two modes of EC etching from the viewpoint of rate balance between the oxidation of SiC by current flow and the removal of formed oxide by electrolyte, and we tried to suppress the formation of etch pits by controlling the etching mode. |
