Abstract

A method for manufacturing a silicon device includes steps of: forming a silicon layer 4a that indicates a second conductivity type on a first surface S1a of a silicon substrate 2a that indicates a first conductivity type; and exposing, after the step, a third surface S3a of the silicon layer 4a for a period of a minimum of 30 minutes and a maximum of 6 hours to an argon-containing atmosphere which is adjusted to temperatures of a minimum of 400° C. and a maximum of 900° C. and pressures of a minimum of 4 MPa and a maximum of 200 MPa.
