  • Patent number: 9263290
    Abstract: Fin structures and methods of manufacturing fin structures using a dual-material sidewall image transfer mask to enable patterning of sub-lithographic features is disclosed. The method of forming a plurality of fins includes forming a first set of fins having a first pitch. The method further includes forming an adjacent fin to the first set of fins. The adjacent fin and a nearest fin of the first set of fins have a second pitch larger than the first pitch. The first set of fins and the adjacent fin are sub-lithographic features formed using a sidewall image transfer process.

  • Patent number: 9202879
    Abstract: In a replacement gate scheme, after formation of a gate dielectric layer, a work function material layer completely fills a narrow gate trench, while not filling a wide gate trench. A dielectric material layer is deposited and planarized over the work function material layer, and is subsequently recessed to form a dielectric material portion overlying a horizontal portion of the work function material layer within the wide gate trench. The work function material layer is recessed employing the dielectric material portion as a part of an etch mask to form work function material portions. A conductive material is deposited and planarized to form gate conductor portions, and a dielectric material is deposited and planarized to form gate cap dielectrics.

  • Publication number: 20140363941
    Abstract: A dielectric disposable gate structure can be formed across a semiconductor material portion, and active semiconductor regions are formed within the semiconductor material portion. Raised active semiconductor regions are grown over the active semiconductor regions while the dielectric disposable gate structure limits the extent of the raised active semiconductor regions. A planarization dielectric layer is formed over the raised active semiconductor regions. In one embodiment, the dielectric disposable gate structure is removed, and a dielectric gate spacer can be formed by conversion of surface portions of the raised active semiconductor regions around a gate cavity. Alternately, an etch mask layer overlying peripheral portions of the disposable gate structure can be formed, and a gate cavity and a dielectric spacer can be formed by anisotropically etching an unmasked portion of the dielectric disposable gate structure. A replacement gate structure can be formed in the gate cavity.

  • Patent number: 8906807
    Abstract: Fin-defining spacers are formed on an array of mandrel structure. Mask material portions can be directionally deposited on fin-defining spacers located on one side of each mandrel structure, while not deposited on the other side. A photoresist layer is subsequently applied and patterned to form an opening, of which the overlay tolerance increases by a pitch of fin-defining spacers due to the mask material portions. Alternately, a conformal silicon oxide layer can be deposited on fin-defining spacers and structure-damaging ion implantation is performed only on fin-defining spacers located on one side of each mandrel structure. A photoresist layer is subsequently applied and patterned to form an opening, from which a damaged silicon oxide portion and an underlying fin-defining spacer are removed, while undamaged silicon oxide portions are not removed. An array of semiconductor fins including a vacancy can be formed by transferring the pattern into a semiconductor layer.

  • Patent number: 8716127
    Abstract: A metal interconnect structure, which includes metal alloy capping layers, and a method of manufacturing the same. The originally deposited alloy capping layer element within the interconnect features will diffuse into and segregate onto top surface of the metal interconnect. The metal alloy capping material is deposited on a reflowed copper surface and is not physically in contact with sidewalls of the interconnect features. The metal alloy capping layer is also reflowed on the copper. Thus, there is a reduction in electrical resistivity impact from residual alloy elements in the interconnect structure. That is, there is a reduction, of alloy elements inside the features of the metal interconnect structure. The metal interconnect structure includes a dielectric layer with a recessed line, a liner material on sidewalls, a copper material, an alloy capping layer, and a dielectric cap.
