    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 may be 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. 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: A connecting circuit structure is provided for a circuit carrier. The circuit connecting structure includes at least two insulating layers, two conductive layers, and one conductive pad, wherein a via hole is formed from each of the insulating layers through corresponding insulating layer. One insulating layer is formed over the other. The conductive pad is disposed between the two insulating layers, and two surfaces of the conductive pad are connected to the two via holes respectively. Two conductive layers are respectively formed in the via hole on a same side of the circuit connecting structure in order to connect to the conductive pad respectively. Since a depth/width ratio of the via hole is reduced according to the circuit connecting structure in the present invention, voids and bubbles are effectively avoided and the reliability of fabricating method thereof is increased.
