    摘要: Methods and associated structures of forming a microelectronic device are described. Those structures may comprise a transistor comprising a metal gate disposed on a gate dielectric that is disposed on a substrate, and a source/drain region disposed adjacent a channel region of the transistor. The source/drain region comprises a source/drain extension comprising a vertex point, wherein a top surface of the channel region is substantially planar with the vertex point.

    摘要: A method of forming a transistor with self-aligned source and drain extensions in close proximity to a gate dielectric layer of the transistor comprises forming a gate stack on a substrate, implanting a dopant into regions of the substrate adjacent to the gate stack, wherein the dopant increases the etch rate of the substrate and defines the location of the source and drain extensions, forming a pair of spacers on laterally opposite sides of the gate stack that are disposed atop the doped regions of the substrate, etching the doped regions of the substrate and portions of the substrate subjacent to the doped regions, wherein an etch rate of the doped regions is higher than an etch rate of the portions of the substrate subjacent to the doped regions, and depositing a silicon-based material in the etched portions of the substrate.

    摘要: A multi-component strain-inducing semiconductor region is described. In an embodiment, formation of such a strain-inducing semiconductor region laterally adjacent to a crystalline substrate results in a uniaxial strain imparted to the crystalline substrate, providing a strained crystalline substrate. In one embodiment, the multi-component strain-inducing material region comprises a first portion and a second portion which are separated by an interface. In a specific embodiment, the concentration of charge-carrier dopant impurity atoms of the two portions are different from one another at the interface.
