    摘要: An electrical fuse has an anode contact on a surface of a semiconductor substrate.

    摘要: A dielectric mandrel structure is formed on a single crystalline semiconductor layer. An amorphous semiconductor material layer is deposited on the physically exposed surfaces of the single crystalline semiconductor layer and surfaces of the mandrel structure. Optionally, the amorphous semiconductor material layer can be implanted with at least one different semiconductor material. Solid phase epitaxy is performed on the amorphous semiconductor material layer employing the single crystalline semiconductor layer as a seed layer, thereby forming an epitaxial semiconductor material layer with uniform thickness. Remaining portions of the epitaxial semiconductor material layer are single crystalline semiconductor fins and thickness of these fins are sublithographic. After removal of the dielectric mandrel structure, the single crystalline semiconductor fins can be employed to form a semiconductor device.

    摘要: A method is provided for making a resistive polycrystalline semiconductor device, e.g., a poly resistor of a microelectronic element such as a semiconductor integrated circuit. The method can include: (a) forming a layered stack including a dielectric layer contacting a surface of a monocrystalline semiconductor region of a substrate, a metal gate layer overlying the dielectric layer, a first polycrystalline semiconductor region adjacent the metal gate layer having a predominant dopant type of either n or p, and a second polycrystalline semiconductor region spaced from the metal gate layer by the first polycrystalline semiconductor region and adjoining the first polycrystalline semiconductor region; and (b) forming first and second contacts in conductive communication with the second polycrystalline semiconductor region, the first and second contacts being spaced apart so as to achieve a desired resistance. In a variation thereof, an electrical fuse is formed which includes a continuous silicide region through which a current can be passed to blow the fuse. Some of the steps of fabricating the poly resistor or the electrical fuse can be employed simultaneously in fabricating metal gate field effect transistors (FETs) on the same substrate.

    摘要: After formation of a gate stack, regions in which a source and a drain are to be formed are recessed through the top semiconductor layer and into an upper portion of a buried single crystalline rare earth oxide layer of a semiconductor-on-insulator (SOI) substrate so that a source trench and drain trench are formed. An embedded single crystalline semiconductor portion epitaxially aligned to the buried single crystalline rare earth oxide layer is formed in each of the source trench and the drain trench to form a recessed source and a recessed drain, respectively. Protrusion of the recessed source and recessed drain above the bottom surface of a gate dielectric can be minimized to reduce parasitic capacitive coupling with a gate electrode, while providing low source resistance and drain resistance through the increased thickness of the recessed source and recessed drain relative to the thickness of the top semiconductor layer.
