Abstract:
1. A method for manufacturing a silicon device, comprising steps of: (a) forming a layer comprised of silicon having a second conductivity type on a surface of a silicon material having a first conductivity type; and (b) exposing, after step (a), a surface of the silicon layer 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, wherein the silicon material includes a silicon area arranged on the surface of the silicon material and having a thickness inwardly of the silicon material from the surface, and the silicon area is formed of β-FeSi
