    Abstract: 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.

    Abstract: 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.

    Abstract: A method includes forming a first fin and a second fin extending above a semiconductor substrate, with a shallow trench isolation (STI) region between them. A space is defined between the first and second fins above a top surface of the STI region. A first height is defined between the top surface of the STI region and top surfaces of the first and second fins. A flowable dielectric material is deposited into the space. The dielectric material has a top surface above the top surface of the STI region, so as to define a second height between the top surface of the dielectric material and the top surfaces of the first and second fins. The second height is less than the first height. First and second fin extensions are epitaxially formed above the dielectric, on the first and second fins, respectively, after the depositing step.
