    Abstract: 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.

    Abstract: Disclosed are semiconductor structures and methods of forming them. The structures include field effect transistors (FETs) with different type conductivities in different levels, respectively, of the same fin, wherein the numbers of FETs in the different levels are different. Specifically, in a fin, a first semiconductor layer has source/drain and channel regions for a first and a second transistor and a second semiconductor layer has source/drain and channel regions for a third transistor with a different type conductivity than first and second transistors. A gate is on the top surface and sides of the first semiconductor layer at the channel region of the first transistor. Another gate has a lower portion on the sides of the first semiconductor layer at the channel region of the second transistor and an upper portion on the top surface and sides of the second semiconductor layer at the channel region of the third transistor.

    Abstract: Methods for forming substantially uniform depth trenches and/or semiconductor fins from the trenches are disclosed. Embodiments of the method may include depositing a germanium including layer over a substrate, the substrate including a plurality of sacrificial semiconductor fins, each pair of sacrificial semiconductor fins separated by a sacrificial pillar. Germanium is diffused from the germanium including layer into the plurality of sacrificial semiconductor fins to a defined uniform depth. The germanium including layer is removed, and the plurality of sacrificial semiconductor fins are etched to the defined uniform depth and selective to the substrate, creating a plurality of trenches having a substantially uniform depth. The trenches can be used to epitaxial grow semiconductor fins having substantially uniform height.

    Abstract: Embodiments of the present invention provide an electrically controlled optical fuse. The optical fuse is activated electronically instead of by the light source itself. An applied voltage causes the fuse temperature to rise, which induces a transformation of a phase changing material from transparent to opaque. A gettering layer absorbs excess atoms released during the transformation.

    Abstract: A mandrel having vertical planar surfaces is formed on a single crystalline semiconductor layer. An epitaxial semiconductor layer is formed on the single crystalline semiconductor layer by selective epitaxy. A first spacer is formed around an upper portion of the mandrel. The epitaxial semiconductor layer is vertically recessed employing the first spacers as an etch mask. A second spacer is formed on sidewalls of the first spacer and vertical portions of the epitaxial semiconductor layer. Horizontal bottom portions of the epitaxial semiconductor layer are etched from underneath the vertical portions of the epitaxial semiconductor layer to form a suspended ring-shaped semiconductor fin that is attached to the mandrel. A center portion of the mandrel is etched employing a patterned mask layer that covers two end portions of the mandrel. A suspended semiconductor fin is provided, which is suspended by a pair of support structures.
