摘要： Methods for uniformly tip doping a silicon body of a non-planar transistor and devices and systems formed by such methods. In one embodiment, a method can include vertical tip ion implantation of a silicon body with at least three surfaces on a substrate followed by conformal deposition of a dielectric material. The dielectric material can be selectively etched to expose a top surface of the silicon body followed by selective re-oxidation of the top surface for form a mask. The remaining dielectric material can be removed followed by angled ion implantation of at least two sidewalls of the silicon body. The mask can be removed resulting in a silicon body with uniform doping.

摘要： A semiconductor device is described. That semiconductor device comprises a high-k gate dielectric layer that is formed over a channel that is positioned within a substrate, and a metal gate electrode that is formed on the high-k gate dielectric layer. The high-k gate dielectric layer has off-state leakage characteristics that are superior to those of a silicon dioxide based gate dielectric, and on-state mobility characteristics that are superior to those of a high-k gate dielectric that comprises an isotropic material.

摘要： A method for making a semiconductor device is described. That method comprises forming on a substrate a dielectric layer and a sacrificial structure that comprises a first layer and a second layer, such that the second layer is formed on the first layer and is wider than the first layer. After the sacrificial structure is removed to generate a trench, a metal gate electrode is formed within the trench.
