  • Publication number: 20150270346
    Abstract: Disclosed herein are various methods of forming replacement gate structures with a recessed channel region. In one example, the method includes forming a sacrificial gate structure above a semiconducting substrate, removing the sacrificial gate structure to thereby define an initial gate opening having sidewalls and to expose a surface of the substrate and performing an etching process on the exposed surface of the substrate to define a recessed channel in the substrate. The method includes the additional steps of forming a sidewall spacer within the initial gate opening on the sidewalls of the initial gate opening to thereby define a final gate opening and forming a replacement gate structure in the final gate opening.

  • Patent number: 8940608
    Abstract: Methods for fabricating integrated circuits are provided. In an embodiment, a method for fabricating an integrated circuit includes providing a semiconductor substrate including a first region of a first doping type, a second region of the first doping type spaced from the first region, a drift region of the first doping type positioned between the first region and the second region, and regions of the opposite doping type. A mask covering both the drift region and the regions of the opposite doping type is formed. Then, a source/drain ion implantation is performed into the first region and the second region. The mask prevents the drift region and the regions of the opposite doping type from receiving the source/drain ion implantation.

  • Patent number: 8598009
    Abstract: A low energy surface is formed by a high temperature anneal of the surfaces of trenches on each side of a gate stack. The material of the semiconductor layer reflows during the high temperature anneal such that the low energy surface is a crystallographic surface that is at a non-orthogonal angle with the surface normal of the semiconductor layer. A lattice mismatched semiconductor material is selectively grown on the semiconductor layer to fill the trenches, thereby forming embedded lattice mismatched semiconductor material portions in source and drain regions of a transistor. The embedded lattice mismatched semiconductor material portions can be in-situ doped without increasing punch-through. Alternately, a combination of intrinsic selective epitaxy and ion implantation can be employed to form deep source and drain regions.
