    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: An extremely thin SOI MOSFET device on an SOI substrate is provided with a back gate layer on a Si substrate superimposed by a thin BOX layer; an extremely thin SOI layer (ETSOI) on top of the thin BOX layer; and an FET device on the ETSOI layer having a gate stack insulated by spacers. The thin BOX is formed under the ETSOI channel, and is provided with a thicker dielectric under source and drain to reduce the source/drain to back gate parasitic capacitance. The thicker dielectric portion is self-aligned with the gate. A void within the thicker dielectric portion is formed under the source/drain region. The back gate is determined by a region of semiconductor damaged by implantation, and the formation of an insulating layer by lateral etch and back filling with dielectric.

    摘要: A method of fabricating a semiconductor device that includes providing a substrate having at least a first semiconductor layer atop a dielectric layer, wherein the first semiconductor layer has a first thickness of less than 10 nm. The first semiconductor layer is etched with a halide based gas at a temperature of less than 675° C. to a second thickness that is less than the first thickness. A second semiconductor layer is epitaxially formed on an etched surface of the first semiconductor layer. A gate structure is formed directly on the second semiconductor layer. A source region and a drain region is formed on opposing sides of the gate structure.

    摘要: Voltage programmable anti-fuse structures and methods are provided that include at least one conductive material island atop a dielectric surface that is located between two adjacent conductive features. In one embodiment, the anti-fuse structure includes a dielectric material having at least two adjacent conductive features embedded therein. At least one conductive material island is located on an upper surface of the dielectric material that is located between the at least two adjacent conductive features. A dielectric capping layer is located on exposed surfaces of the dielectric material, the at least one conductive material island and the at least two adjacent conductive features. When the anti-fuse structure is in a programmed state, a dielectric breakdown path is present in the dielectric material that is located beneath the at least one conductive material island which conducts electrical current to electrically couple the two adjacent conductive features.
