    摘要: A semiconductor device is formed by first providing a dual gate semiconductor device structure having FET pair precursors, which includes an nFET precursor and a pFET precursor, wherein each of the nFET precursor and the pFET precursor includes a dummy gate structure. At least one protective layer is deposited across the FET pair precursors, leaving the dummy gate structures exposed. The dummy gate structure is removed from one of the nFET precursor and the pFET precursor to create therein one of an nFET gate hole and a pFET gate hole, respectively. A fill is deposited into the formed one of the nFET gate hole and the pFET gate.

    摘要: A device and method for improving performance of a transistor includes gate structures formed on a substrate having a spacing therebetween. The gate structures are formed in an operative relationship with active areas formed in the substrate. A stress liner is formed on the gate structures. An angled ion implantation is applied to the stress liner such that ions are directed at vertical surfaces of the stress liner wherein portions of the stress liner in contact with the active areas are shielded from the ions due to a shadowing effect provided by a height and spacing between adjacent structures.

    摘要: A method for processing a semiconductor fin structure is disclosed. The method includes thermal annealing a fin structure in an ambient containing an isotope of hydrogen. Following the thermal annealing step, the fin structure is etched in a crystal-orientation dependent, self-limiting, manner. The crystal-orientation dependent etch may be selected to be an aqueous solution containing ammonium hydroxide (NH4OH). The completed fin structure has smooth sidewalls and a uniform thickness profile. The fin structure sidewalls are {110} planes.

    摘要: A method for fabrication of features for an integrated circuit includes patterning a first semiconductor structure on a surface of a semiconductor device, and epitaxially growing semiconductor material on opposite sides of the first semiconductor structure to form fins. A first angled ion implantation is applied to one side of the first semiconductor structure to dope a respective fin on the one side. The first semiconductor structure is selectively removed to expose the fins. Fin field effect transistors are formed using the fins.

    摘要: Disclosed is an improved double patterning method for forming openings (e.g., vias or trenches) or mesas on a substrate. This method avoids the wafer topography effects seen in prior art double patterning techniques by ensuring that the substrate itself is only subjected to a single etch process. Specifically, in the method, a first mask layer is formed on the substrate and processed such that it has a doped region and multiple undoped regions within the doped region. Then, either the undoped regions or the doped region can be selectively removed in order to form a mask pattern above the substrate. Once the mask pattern is formed, an etch process can be performed to transfer the mask pattern into the substrate. Depending upon whether the undoped regions are removed or the doped region is removed, the mask pattern will form openings (e.g., vias or trenches) or mesas, respectively, on the substrate.
