Abstract
PURPOSE:To suppress the thickness unevenness of a polishing surface and its roughness to be decreased further to reduce a margin for polishing in an after process of mirror polishing or the like by accurately cutting at least one of the surfaces of a wafer before its final mirror polishing is performed. CONSTITUTION:A wafer, to which etching work is applied, is mounted to a fine cutting machine by using a vacuum chuck, and one of the surfaces of this wafer is fine cut by a diamond tool, forming the thickness unevenness to 1.0mu or less while the surface roughness to a degree of 0.002-1.0mu. Next performing mirror polishing with a margin about 0.1-1.0mu, the mirror surfaced wafer with its thickness unevenness about 1mu or less is obtained.
