摘要: In a semiconductor device having a fuse and an etching stopper film covering the fuse, an optical window exposing the etching stopper film and a contact hole exposing a conductor pattern are formed simultaneously. By applying a dry etching process further to the etching stopper film, an insulation film covering the fuse is exposed in the optical window.
