    Abstract: Uniform fin recessing for the situation of recessing nonadjacent fins and the situation of recessing adjacent fins includes providing a starting semiconductor structure, the structure including a semiconductor substrate, multiple fins coupled to the substrate, each fin having a hard mask layer thereover and being surrounded by isolation material. The hard mask layer is then removed over some of the fins, at least partially removing the some of the raised structures, the at least partially removing creating openings, and filling the openings with an optical planarization layer (OPL) material.

    Abstract: A method that involves forming a high-k gate insulation layer, a work-function adjusting metal layer and a metal protection layer in first and second replacement gate cavities, wherein the metal protection layer is formed so as to pinch-off the first gate cavity while leaving the second gate cavity partially un-filled, forming a first bulk conductive metal layer in the un-filled portion of the second gate cavity, removing substantially all of the metal protection layer in the first gate cavity while leaving a portion of the metal protection layer in the second gate cavity, forming a second conductive metal layer within the first and second replacement gate cavities, recessing the conductive metal layers so as to define first and second gate-cap cavities in the first and second replacement gate cavities, respectively, and forming gate cap layers within the first and second gate-cap cavities.

    Abstract: One method disclosed includes, among other things, forming a structure comprised of an island of a first insulating material positioned between the gate structures above the source/drain region and under a masking layer feature of a patterned masking layer, forming a liner layer that contacts the island of insulating material and the masking layer feature, selectively removing the masking layer feature to thereby form an initial opening that is defined by the liner layer, performing at least one isotropic etching process through the initial opening to remove the island of first insulating material and thereby define a contact opening that exposes the source/drain region, and forming a conductive contact structure in the contact opening that is conductively coupled to the source/drain region.

    Abstract: Dummy gates are removed from a pre-metal layer to produce a first opening (with a first length) and a second opening (with a second length longer than the first length). Work function metal for a metal gate electrode is provided in the first and second openings. Tungsten is deposited to fill the first opening and conformally line the second opening, thus leaving a third opening. The thickness of the tungsten layer substantially equals the length of the first opening. The third opening is filled with an insulating material. The tungsten is then recessed in both the first and second openings using a dry etch to substantially a same depth from a top surface of the pre-metal layer to complete the metal gate electrode. Openings left following the recess operation are then filled with a dielectric material forming a cap on the gate stack which includes the metal gate electrode.
