    摘要: A method includes forming first and second fins of a finFET extending above a semiconductor substrate, with a shallow trench isolation (STI) region in between, and a distance between a top surface of the STI region and top surfaces of the first and second fins. First and second fin extensions are provided on top and side surfaces of the first and second fins above the top surface of the STI region. Material is removed from the STI region, to increase the distance between the top surface of the STI region and top surfaces of the first and second fins. A conformal stressor dielectric material is deposited over the fins and STI region. The conformal dielectric stressor material is reflowed, to flow into a space between the first and second fins above a top surface of the STI region, to apply stress to a channel of the finFET.

    摘要: Provided is a high-k metal gate structure formed over a semiconductor fin. A nitride layer is formed over the gate structure and the semiconductor fin, using two separate deposition operations, the first forming a very thin nitride film. Implantation operations such as an LDD or a PKT implant, are carried out in between the two nitride film deposition operations. The first nitride film may be SiNx or SiCNx and the second nitride film is SiCNx with a low wet etch rate in H3PO4 and dilute HF acid. The nitride films may be combined to form low wet etch rate spacers enabling further processing operations to be carried out without damaging underlying structures and without requiring the formation of further dummy spacers. Further processing operations include epitaxial silicon/SiGe processing sequences and source/drain implanting operations carried out with the low etch rate spacers intact.

    摘要: An integrated circuit device includes a gate region extending above a semiconductor substrate and extending in a first longitudinal direction. A first fin has a first sidewall that extends in a second longitudinal direction above the semiconductor substrate such that the first fin intersects the gate region. A second fin has a second sidewall extending in the second direction above the semiconductor substrate such that the second fin intersects the gate region. A shallow trench isolation (STI) region is formed in the semiconductor substrate between the first and second sidewalls of the first and second fins. A conductive layer disposed over the first insulating layer and over top surfaces of the first and second fins. A first insulating layer is disposed between an upper surface of the STI region and a lower surface of the conductive layer to separate the STI region from the conductive layer.
