摘要： Source and drain extension regions and source side halo region and drain side halo region are formed in a top semiconductor layer aligned with a gate stack on an SOI substrate. A deep source region and a deep drain region are formed asymmetrically in the top semiconductor layer by an angled ion implantation. The deep source region is offset away from one of the outer edges of the at least spacer to expose the source extension region on the surface of the semiconductor substrate. A source metal semiconductor alloy is formed by reacting a metal layer with portions of the deep source region, the source extension region, and the source side halo region. The source metal semiconductor alloy abuts the remaining portion of the source side halo region, providing a body contact tied to the deep source region to the partially depleted SOI MOSFET.

摘要： A method is provided to fabricate a semiconductor device, where the method includes providing a substrate comprised of crystalline silicon; implanting a ground plane in the crystalline silicon so as to be adjacent to a surface of the substrate, the ground plane being implanted to exhibit a desired super-steep retrograde well (SSRW) implant doping profile; annealing implant damage using a substantially diffusionless thermal annealing to maintain the desired super-steep retrograde well implant doping profile in the crystalline silicon and, prior to performing a shallow trench isolation process, depositing a silicon cap layer over the surface of the substrate. The substrate may be a bulk Si substrate or a Si-on-insulator substrate. The method accommodates the use of an oxynitride gate stack structure or a high dielectric constant oxide/metal (high-K/metal) gate stack structure. The various thermal processes used during fabrication are selected/controlled so as to maintain the desired super-steep retrograde well implant doping profile in the crystalline silicon.

摘要： A method is provided for fabricating a semiconductor device. According to the method, a semiconductor layer is formed over a semiconductor-on-insulator substrate, and a gate is formed on the semiconductor layer. Source and drain extension regions and a deep drain region are formed in the semiconductor layer. A deep source region is formed in the semiconductor layer. A drain metal-semiconductor alloy contact is located on the upper portion of the deep drain region and abutting the drain extension region. A source metal-semiconductor alloy contact abuts the source extension region. The deep source region is located below and contacts a first portion of the source metal-semiconductor alloy contact. The deep source region is not located below and does not contact a second portion of the source metal-semiconductor alloy contact. The second portion of the source metal-semiconductor alloy contact is an internal body contact that directly contacts the semiconductor layer.
