PROCESS FOR PRODUCING SEMICONDUCTOR DEVICE AND SEMICONDUCTOR DEVICE |
摘要 |
A process for producing a semiconductor device includes: forming an SiC epitaxial layer on an SiC substrate; implanting the epitaxial layer with ions; forming a gettering layer having a higher defect density than a defect density of the SiC substrate; and carrying out a heat treatment on the epitaxial layer. The semiconductor device includes an SiC substrate, an SiC epitaxial layer formed on the SiC substrate, and a gettering layer having a higher defect density than a defect density of the SiC substrate. |

1. A process for producing a semiconductor device, the process comprising:
forming an SiC epitaxial layer on an SiC substrate, wherein the epitaxial layer is heat treated in the process; implanting ions into the epitaxial layer; forming a gettering layer having a higher defect density than a defect density of the SiC substrate; and conducting gettering at 1500° C. or higher after the gettering layer is formed. |
