发明名称 Silicon wafer
摘要 The present invention provides a method for producing a silicon wafer characterized in that at least one surface of the wafer is subjected to a multi-step polishing process, in which a heat treatment in a mixed gas atmosphere of hydrogen and argon through use of a rapid heating/rapid cooling apparatus is substituted for a final polishing in the multi-step polishing process, and a silicon wafer produced by the method. Thereby, there can be provided a silicon wafer in high productivity wherein there is neither mechanical damages nor scratches on the surface of the wafer, surface roughness is significantly improved, and there is no slip dislocation.
