Abstract
A semiconductor integratd circuit device includes fuse elements formed on an element isolation insulating film, and an insulating film, an interlayer insulating film and a silicon nitride film successively formed over the fuse elements. An opening region extends through the silicon nitride film into the interlayer insulating film above the fuse elements, and openings formed in the interlayer insulating film are positioned on both sides of middle portions of the fuse elements. The openings facilitate blowing off of the insulating film during laser cutting of the fuse elements, reducing physical damage to the element isolation insulating film under the fuse elements.
