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.
