    摘要: Antireflective residues during pattern transfer and consequential short circuiting are eliminated by employing an underlying sacrificial layer to ensure complete removal of the antireflective layer. Embodiments include forming a hard mask layer over a conductive layer, e.g., a silicon substrate, forming the sacrificial layer over the hard mask layer, forming an optical dispersive layer over the sacrificial layer, forming a silicon anti-reflective coating layer over the optical dispersive layer, forming a photoresist layer over the silicon anti-reflective coating layer, where the photoresist layer defines a pattern, etching to transfer the pattern to the hard mask layer, and stripping at least the optical dispersive layer and the sacrificial layer.

    摘要: A methodology for varying the depth of a design feature on a semiconductor wafer. Vias are formed according to design requirements. Nonfunctioning vias may also be placed at a location with respect to a design feature. After vias are formed, the semiconductor wafer is caused to undergo an ashing process followed by the application of an organic planarizing layer. The design features are then formed. If the depth of the design features does not meet design requirements, another semiconductor wafer may be processed to meet design requirements by varying the ashing conditions, choice of organic planarizing layer and/or the nonfunctioning and/or functioning via placement. Design features having various depths on a single semiconductor wafer may be formed with a single lithographic process.

    摘要: According to one exemplary embodiment, a method for forming a field-effect transistor on a substrate, where the substrate includes a high-k dielectric layer situated over the substrate and a gate electrode layer situated over the high-k dielectric layer, comprises a step of etching the gate electrode layer and the high-k dielectric layer to form a gate stack, where the gate stack comprises a high-k dielectric segment situated over the substrate and a gate electrode segment situated over the high-k dielectric segment. According to this exemplary embodiment, the method further comprises performing a nitridation process on the gate stack. The nitridation process can be performed by, for example, utilizing a plasma to nitridate sidewalls of the gate stack, where the plasma comprises nitrogen. The nitridation process can cause nitrogen to enter the high-k dielectric segment and form an oxygen diffusion barrier in the high-k dielectric segment, for example.

    摘要: Methods for fabricating integrated circuits using tailored chamfered gate liner profiles are provided. In an exemplary embodiment, a method for fabricating an integrated circuit includes forming a dummy gate electrode overlying a semiconductor substrate and forming a liner on sidewalls of the dummy gate electrode. A dielectric material is deposited overlying the dummy gate electrode, the liner, and the substrate. The dummy gate electrode is exposed by chemical mechanical planarization. A portion of the dummy gate electrode is removed and the liner is isotropically etched such that it has a chamfered surface. A remainder of the dummy gate electrode is removed to form an opening that is filled with a metal.
