Filed: 1989-02-21
Abstract: PURPOSE:To prevent a substratum of a wafer peripheral part from being exposed during an etching operation by providing a cutoff means composed of a chemical-resistant material which prevents the wafer peripheral part from being etched. CONSTITUTION:A clamp 11 with which a cathode 4 as a wafer-mounting electrode of a single wafer etching apparatus used to treat wafers individually is prepared. A chemical-resistant material which does not have a bad influence during an etching operation, such as quartz, a ceramic or the like, is used as a material for the clamp. During the etching operation, a shielding part 11a is installed in such a way that a prescribed width is covered with the clamp 11 from an outer periphery of a wafer 1 toward its inside; the surface of the wafer is covered so as to shield a wafer peripheral part 1a. Since the wafer peripheral part 1a is covered with the shielding part 11a during the etching operation, it is not exposed to reactive ions, and an insulating film formed at a peripheral part of the wafer 1 is not etched. Thereby, when a contact hole is made, it is possible to prevent a substratum of the wafer peripheral part 1a from being exposed.
