ABSTRACT:
In a semiconductor device including an anti-fuse element, a first electrode layer is formed on a semiconductor substrate. A first insulating layer is formed only on the first electrode layer for insulating the first electrode layer. An anti-fuse insulating film is coated on at least one side wall portion of each of the first electrode layer and the first insulating layer. A second electrode layer is formed on the anti-fuse insulating film, and the first and second electrode layers and the anti-fuse insulating film constitute the anti-fuse element.
