Title: Method for manufacturing semiconductor wafer whose one surface is coated and finished
Inventor: PIETSCH GEORG
IPC: B24B37/08
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To make compatible the flatness, plane parallelism, and smoothness to those of an uncoated double-sided finish wafer regardless of a single-surface coating by finishing both surfaces of a semiconductor wafer simultaneously, then performing at least one coating on the single surface, and then performing a double-sided finishing. SOLUTION: A semiconductor wafer becomes a wafer shape that is optimum, namely especially flat, parallel in terms of surfaces, smooth, and defectless by a treatment for giving a double-sided finishing to be executed in a process (a). In a coating by a process (b), one or a plurality of layers are generated on the single surface of the semiconductor wafer. This coating becomes possible by either known method of the deposition or generation of layer with especially a chemical or physical conversion such as thermal oxidation or doping as a means. In a process (c), the semiconductor wafer is subjected to a second double- sided finishing, thus eliminating both of a damage on uncoated surface that may occur during coating and the non-uniformity in the coated surface.
