Abstract:
1. A method of manufacturing a semiconductor device comprising: forming a first insulating film supported by a semiconductor substrate; forming an aluminum layer supported by said first insulating film; etching said aluminum layer to form a bonding pad and a fuse element; depositing by plasma chemical vapor deposition a second insulating film, covering said bonding pad and said fuse element, said second insulating film having a planar portion, between said fuse element and said bonding pad, and ridged portions, opposite said fuse element; depositing by plasma chemical vapor deposition a third insulating film covering said second insulating film; etching said third insulating film to form a first hole exposing a first region of said second insulating film, opposite said fuse element, and a second hole exposing a second region of said second insulating film, opposite at least part of said bonding pad; and etching said second insulating film to expose at least part of said bonding pad, wherein
