Abstract

PURPOSE: To avert overetching by masking with a photoresist film and etching regions other than one region, checking the end point thereof from the water repellency of the exposed semiconductor region and likewise etching other regions as well in etching the longitudinal and transverse scribing regions provided in a Si wafer.
