| 摘要 |
A method for producing a silicon wafer for epitaxial substrate which includes a first step of performing thermal oxidization on a silicon wafer containing boron atoms no less than 1E19 atoms/cm3, thereby forming a silicon oxide film on the surface of the silicon wafer, a second step of peeling off the silicon oxide film, and a third step of performing heat treatment on the silicon wafer in a hydrogen atmosphere.
