Abstract:
1. A programmable device, comprising: an insulator located on a substrate; a semiconductor material structure located on said insulator, said semiconductor material structure including a first end portion, a second end portion, and a fuse link, wherein said fuse link laterally contacts said first end portion and said second end portion and has a pair of parallel sidewalls separated by a substantially uniform width throughout an entirety thereof, said first end portion comprises a rectangular portion and a plurality of integral triangular-shaped portions, said rectangular portion includes a pair of coplanar sidewalls that are coplanar with each other, contacting sidewalls of said fuse link, and substantially perpendicular to said pair of parallel sidewalls, wherein said plurality of integral triangular-shaped portions is laterally spaced from said pair of parallel sidewalls by said pair of coplanar sidewalls, and sidewalls of said plurality of integral triangular-shaped portions, said pair of coplanar sidewalls, and said pair of parallel sidewalls form openings which face generally toward said second end portion; and a metallic material structure located on an upper surface of said semiconductor material structure and including a metallic material that is physically migratable along said upper surface responsive to an electrical current-I flowable through said semiconductor material structure and through said metallic material structure.
