Abstract:
1. A semiconductor device, comprising: a first insulating layer formed on a semiconductor layer; a conductive line formed in the first insulating layer; a protective layer formed on the conductive line; one or more fuses formed in the first insulating layer and electrically connected to the conductive line; a fuse protective layer formed on the one or more fuses, and spaced apart from the protective layer; and a second insulating layer directly formed on a top surface of the protective layer and directly formed on a portion of a top surface of the first insulating layer and wherein the second insulating layer has an opening therein which exposes a region of the first insulating layer including the fuse protective layer formed on the one or more fuses and which also exposes a gap formed on a portion of the top surface of the first insulating layer between the protective layer and the fuse protective layer.
