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