Abstract: When the film thickness of an insulating film on a fuse connected to a circuit is not uniform within a wafer surface, there was a problem that disconnection of the fuse might become insufficient due to the insufficient intensity of a laser or disconnection of even an adjacent fuse due to excessive laser irradiation might occur. Further, a problem also occurred that after disconnection of the fuse, moisture entered from exterior through the region in which the fuse has been disconnected, so that the quality of a film underlying the fuse was adversely affected.

The SiON film having a uniform and desired film thickness is thereby formed on the fuse.
