Abstract: Methods of forming transistor devices having an increased gate width dimension are disclosed. In one example, the method includes forming an isolation structure in a semiconducting substrate, wherein the isolation structure defines an active region in the substrate, performing an ion implantation process on the isolation structure to create a damaged region in the isolation structure and, after performing the implantation process, performing an etching process to remove at least a portion of the damaged region to define a recess in the isolation structure, wherein a portion of the recess extends below an upper surface of the substrate and exposes a sidewall of the active region. The method further includes forming a gate insulation layer above the active region, wherein a portion of the insulation layer extends into the recess, and forming a gate electrode above the insulation layer, wherein a portion of the gate electrode extends into the recess.

Abstract: Disclosed herein are various methods of forming faceted stress-inducing stressors proximate the gate structure of a transistor. In one example, a method includes forming a first recess in an active region of a semiconducting substrate, forming a first semiconductor material in the first recess and forming a gate structure above the first semiconductor material. In this example, the method includes the additional steps of performing a crystalline orientation-dependent etching process on the first semiconductor material to define a plurality of second recesses proximate the gate structure, wherein each of the second recesses has a faceted edge, and forming a first region of stress-inducing semiconductor material in each of the second recesses, wherein each of the first regions of stress-inducing semiconductor material has a faceted edge that engages a corresponding faceted edge in one of the second recesses.
