Kazuhiko Yamamoto, Yoshiaki Matsushita, Masaru Kanamori, Kazutoshi Nagasawa, Naotsugu Yoshihiro, Seigo Kishino: Method of forming nondefective zone in silicon single crystal wafer by two stage-heat treatment. VLSI Technology Research Association, Finnegan Henderson Farabow Garrett & Dunner, February 9, 1982: US04314595 (82 worldwide citation)

A silicon single crystal wafer is subjected to two-stage heat treatment. In the first-stage it is heated at a temperature within the range of between 500.degree. C. and 1,000.degree. C. Subsequently the thus heated wafer is heated at a temperature higher than that at the first stage. Thus, a nondefe ...
