ABSTRACT:
A semiconductor memory device has fuses coated with a protecting layer. The protecting layer is selectively etched to open windows so as to expose narrow center portions of the fuses. After the opening of the center windows, the fusing operation of the fuses is carried out to open a gap in the center window portion of the fuse material. In a preferred embodiment, another protective layer is then added to fill the gaps in the blown fuses.
