    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: 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.

    Abstract: A method of forming aluminum guard structures in copper interconnect structures, used to protect the copper interconnect structures from a laser write procedure, performed to an adjacent copper fuse element, has been developed. The method features forming guard structure openings in an upper level of the copper interconnect structures, in a region adjacent to a copper fuse element. Deposition and patterning of an aluminum layer result in the formation of aluminum guard structures, located in the guard structure openings. The aluminum guard structures protect the copper interconnect structures from the oxidizing and corrosive effects of oxygen, fluorine and water ions, which are generated during a laser write procedure, performed to the adjacent copper fuse element.

    Abstract: A method for incorporating an ion implanted channel stop layer under field isolation for a twin-well CMOS process is described in which the layer is placed directly under the completed field isolation by a blanket boron ion implant over the whole wafer. The channel stop implant follows planarization of the field oxide and is thereby essentially at the same depth in both field and active regions. Subsequently implanted p- and n-wells are formed deeper than the channel stop layer, the n-well implant being of a sufficiently higher dose to over compensate the channel stop layer, thereby removing it's effect from the n-well. A portion of the channel stop implant under the field oxide adjacent the p-well provides effective anti-punchthrough protection with only a small increase in junction capacitance. The method is shown for, and is particularly effective in, processes utilizing shallow trench isolation.

    Abstract: A described method includes providing a semiconductor substrate. A first gate structure is formed on the semiconductor substrate and a sacrificial gate structure formed adjacent the first gate structure. The sacrificial gate structure may be used to form a metal gate structure using a replacement gate methodology. A dielectric layer is formed overlying the first gate structure and the sacrificial gate structure. The dielectric layer has a first thickness above a top surface of the first gate structure and a second thickness, less than the first thickness, above a top surface of the sacrificial gate structure. (See, e.g., FIGS. 5, 15, 26). Thus, a subsequent planarization process of the dielectric layer may not contact the first gate structure.

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.

    Abstract: A process for fabricating input/output, N channel, (I/O NMOS) devices, featuring an ion implanted nitrogen region, used to reduce hot carrier electron, (HEC), injection, has been developed. The process features implanting a nitorgen region, at the interface of an overlying silicon oxide layer, and an underlying lightly doped source/drain, (LDD), region. The implantation procedure can either be performed prior to, or after, the deposition of a silicon oxide liner layer, in both cases resulting in a desired nitrogen pile-up at the oxide-LDD interface, as well as resulting, in a more graded LDD profile. An increase in the time to fail, in regards to HCE injection, for these I/O NMOS devices, is realized, when compared to counterparts fabricated without the nitrogen implantation procedure.
