  • Patent number: 8183138
    Abstract: Methods for forming nanodots and/or a patterned material are provided. One such method involves forming a first patterning material over a base. Blades of a nanoimprint lithography template are placed within the first patterning material, wherein the blades extend along the base in a first direction. With the blades within the first patterning material, the first patterning material are cured. The blades are removed from the first patterning material to form a patterned first patterning material. The base is etched using the patterned first patterning material as a pattern to form openings in the base. The patterned first patterning material is removed from the base. A second patterning material is formed over the base and within the openings in the base. Blades of a nanoimprint lithography template are placed within the second patterning material, wherein the blades extend along the base in a second direction, which is generally perpendicular with respect to the first direction.

  • Patent number: 8163640
    Abstract: A dielectric material layer is formed on a metal gate layer for a metal gate electrode, and then lithographically patterned to form a dielectric material portion, followed by formation of a polycrystalline semiconductor layer thereupon. A semiconductor device employing a metal gate electrode is formed in a region of the semiconductor substrate containing a vertically abutting stack of the metal gate layer and the polycrystalline semiconductor layer. A material stack in the shape of an electrical fuse is formed in another region of the semiconductor substrate containing a vertical stack of the metal gate layer, the dielectric material portion, and the polycrystalline semiconductor layer. After metallization of the polycrystalline semiconductor layer, an electrical fuse containing a polycrystalline semiconductor portion and a metal semiconductor alloy portion is formed over the dielectric material portion that separates the electrical fuse from the metal gate layer.

  • Patent number: 8158519
    Abstract: In a method of manufacturing a non-volatile memory cell, a self-aligned metal silicide is used in place of a conventional tungsten metal layer to form a polysilicon gate, and the self-aligned metal silicide is used as a connection layer on the polysilicon gate. By using the self-aligned metal silicide to form the polysilicon gate, the use of masks in the etching process may be saved to thereby enable simplified manufacturing process and accordingly, reduced manufacturing cost. Meanwhile, the problem of resistance shift caused by an oxidized tungsten metal layer can be avoided.
