  • Patent number: 8004060
    Abstract: A metal layer and a semiconductor layer are sequentially deposited on a substrate. The semiconductor layer and the metal layer are lithographically patterned to form a stack of a semiconductor portion and a metal gate portion, which is preferably performed concurrently with formation of at least one metal gate stack. In one embodiment, the size of the semiconductor portion is reduced and a metal semiconductor alloy portion is formed on the semiconductor portion by metallization. In a first electrical antifuse formed thereby, the metal semiconductor alloy portion may be electromigrated to form a short between the metal semiconductor alloy portion and the metal gate portion. In another embodiment, two disjoined metal semiconductor alloy portions are formed on the semiconductor portion. In a second electrical antifuse formed thereby, the metal semiconductor alloy portion may be electromigrated to form a short between the two previously disjoined metal semiconductor alloy portions.

  • Patent number: 7943493
    Abstract: A contiguous block of a stack of two heterogeneous semiconductor layers is formed over an insulator region such as shallow trench isolation. A portion of the contiguous block is exposed to an etch, while another portion is masked during the etch. The etch removes an upper semiconductor layer selective to a lower semiconductor layer in the exposed portion. The etch mask is removed and the entirety of the lower semiconductor layer within the exposed region is metallized. A first metal semiconductor alloy vertically abutting the insulator region is formed, while exposed surfaces of the stack of two heterogeneous semiconductor layers, which comprises the materials of the upper semiconductor layer, are concurrently metallized to form a second metal semiconductor alloy. An inflection point for current and, consequently, a region of flux divergence are formed at the boundary of the two metal semiconductor alloys.
