Abstract:
A method of fabricating of a grooved fuse comprised of a plug layer comprising the steps of:a) providing a semiconductor structure having a fuse area, and a device area;b) forming a first conductive layer over said fuse area; said first conductive layer comprised of first and second conductive strips;c) forming a plurality of insulating layers having (a) fuse plug contacts to said first and second conductive strips, and (b) device plugs in said device area; said fuse plug contacts electrically connected to said first and second conductive strips; said fuse plug contacts composed of a non-corroding material;d) forming a dielectric layer over said plurality of insulating layers and fuse plug contacts;e) etching a fuse via opening in said dielectric layer;f) forming a plug fuse in said fuse via opening and simultaneously forming plugs in said device area; said plug fuse is electrically connected to said fuse plug contacts;g) forming a plurality of passivation layers, metal layers and plugs, over said plug fuse and said dielectric layer to form device interconnects in said device area.
