Abstract: At least one method, apparatus and system disclosed herein for forming a finFET device having a pass-through structure. A first gate structure and a second gate structure are formed on a semiconductor wafer. A first active area is formed on one end of the first and second gate structures. A second active area is formed on the other end of the first and second gate structures. A trench silicide (TS) structure self-aligned to the first and second gate structures is formed. The TS structure is configured to operatively couple the first active area to the second active area.

Abstract: Embodiments of the present invention provide improved methods of contact formation. A self aligned contact scheme with reduced lithography requirements is disclosed. This reduces the risk of shorts between source/drains and gates, while providing improved circuit density. Cavities are formed adjacent to the gates, and a fill metal is deposited in the cavities to form contact strips. A patterning mask is then used to form smaller contacts by performing a partial metal recess of the contact strips.

Abstract: A method includes electrically connecting a plurality of cells of a standard cell library to a power rail. A contact area is deposited to connect a first active area and a second active area of a cell of a plurality cells. The first area and the second area are located on opposite sides of the rail and electrically connected to different drains. The contact area is electrically connected to the power rail using a via. The contact area is masked to remove a portion of the contact area to electrically separate the first active are from the second active area.

Abstract: At least one method, apparatus and system disclosed involves providing an integrated circuit having metal feature flyover over an middle-of-line (MOL) feature. A first location for a non-contact intersection region between a first middle of line (MOL) interconnect feature and a metal feature in a functional cell is determined. A dielectric feature is formed over the first MOL interconnect feature at the first location. The metal feature is formed over the dielectric layer, the dielectric layer providing a predetermined amount of voltage isolation between the first MOL interconnect feature and the metal feature.

One method includes, for instance: obtaining an intermediate semiconductor device; performing a first lithography to pattern a first shape; performing a second lithography to pattern a second shape overlapping a portion of the first shape; processing the first shape and the second shape to form an isolation region at the overlap; and forming four regions separated by the isolation region. An intermediate semiconductor device is also disclosed.

Abstract: Embodiments of the present invention provide an improved semiconductor structure and methods of fabrication that provide transistor contacts that are self-aligned in two dimensions. Two different capping layers are used, each being comprised of a different material. The two capping layers are selectively etchable to each other. One capping layer is used for gate coverage while the other capping layer is used for source/drain coverage. Selective etch processes open the desired gates and source/drains, while block masks are used to cover elements that are not part of the connection scheme. A metallization line (layer) is deposited, making contact with the open elements to provide electrical connectivity between them.
