Abstract

A semiconductor device has a field insulating film provided on a semiconductor substrate, and a fuse provided on the field insulating film and having a fuse trimming laser irradiation portion and fuse terminals. The semiconductor device further includes an intermediate insulating film covering the fuse, a first TEOS layer on the intermediate insulating film, an SOG layer for planarizing the first TEOS layer, a second TEOS layer on the SOG layer and on the first TEOS layer, a protective film on the second TEOS layer, and an opening portion above the fuse trimming laser irradiation portion in a region from the protective film to the first TEOS layer. A seal ring is provided on the intermediate insulating film so as to surround the opening portion. The seal ring is disposed over the fuse so as to overlap each of the fuse terminals in plan view.
