    摘要: Asymmetric FinFET devices and methods for fabricating such devices are provided. In one embodiment, a method includes providing a semiconductor substrate comprising a plurality of fin structures formed thereon and depositing a conformal liner over the fin structures. A first portion of the conformal liner is removed, leaving a first space between the fins structures and forming a first metal gate in the first space between the fin structures. A second portion of the conformal liner is removed, leaving a second space between the fin structures and forming a second metal gate in the second space between the fin structures.

    摘要: One illustrative method disclosed herein includes removing a portion of a sacrificial sidewall spacer to thereby expose at least a portion of the sidewalls of a sacrificial gate electrode and forming a liner layer on the exposed sidewalls of the sacrificial gate electrode. In this example, the method also includes forming a sacrificial gap fill material above the liner layer, exposing and removing the sacrificial gate electrode to thereby define a gate cavity that is laterally defined by the liner layer, forming a replacement gate structure, removing the sacrificial gap fill material and forming a low-k sidewall spacer adjacent the liner layer. A device is also disclosed that includes a gate cap layer, a layer of silicon nitride or silicon oxynitride positioned on each of two upstanding portions of a gate insulation layer and a low-k sidewall spacer positioned on the layer of silicon nitride or silicon oxynitride.

    摘要: A technique relates to fabricating a macro for measurements utilized in dual spacer, dual epitaxial transistor devices. The macro is fabricated according to a fabrication process. The macro is a test layout of a semiconductor structure having n-p bumps at junctions between NFET areas and PFET areas. Optical critical dimension (OCD) spectroscopy is performed to obtain the measurements of the n-p bumps on the macro. An amount of chemical mechanical polishing is determined to remove the n-p bumps on the macro based on the measurements of the n-p bumps on the macro. Chemical mechanical polishing is performed to remove the n-p bumps on the macro. The amount previously determined for the macro is utilized to perform chemical mechanical polishing for each of the dual spacer, dual epitaxial layer transistor devices having been fabricated under the fabrication process of the macro in which the fabrication process produced the n-p bumps.
