  • Patent number: 10319855
    Abstract: A method for reducing series resistance for transistors includes forming a conductive gate over and insulated from a semiconductor substrate, forming source and/or drain extension regions within the substrate and adjacent to respective source and/or drain regions, and forming source and/or drain regions within the substrate. The source and/or drain extension regions are formed from a material alloyed with a first dopant and a second dopant, the first dopant configured to increase a lattice structure of the material forming the source and/or drain extension regions.
    Type: Grant
    Filed: September 25, 2017
    Date of Patent: June 11, 2019

  • Patent number: 10229910
    Abstract: A method for forming a semiconductor device includes blocking a first region of a wafer and forming a plurality of fins in a second region of the wafer. A protective conformal mask layer is deposited over the plurality of fins in the second region, the second region is blocked, and a plurality of fins are formed in the first region of the wafer using a variety of wet and/or dry etching procedures. The protective conformal mask layer protects the plurality of fins in the second region from the variety of wet and/or dry etching procedures that are used to form the plurality of fins in the first region.

  • Publication number: 20180197858
    Abstract: A method for fabricating fin field effect transistors comprises creating a pattern of self-aligned small cavities for P-type material growth using at least two hard mask layers, generating a pre-defined isolation area around each small cavity using a vertical spacer, selectively removing N-type material from the self-aligned small cavities, and growing P-type material in the small cavities. The P-type material may be silicon germanium (SiGe) and the N-type material may be tensile Silicon (t-Si). The pattern of self-aligned small cavities for P-type material growth is created by depositing two hard mask materials over a starting substrate wafer, selectively depositing photo resist over a plurality N-type areas, reactive ion etching to remove the second hard mask layer material over areas not covered by photo resist to create gaps in second hard mask layer, and removing the photo resist to expose the second hard mask material in the N-type areas.

  • Patent number: 9666486
    Abstract: A semiconductor structure is provided in which the diffusion of arsenic is retarded. The structure includes a strain relaxed silicon germanium alloy buffer layer located on a surface of a silicon substrate. A boron-containing p-well region is located in a first region of a carbon doped silicon germanium alloy layer and on a first portion of the strain relaxed silicon germanium alloy buffer layer, and a phosphorus-containing n-well region is located in a second region of the carbon doped silicon germanium alloy layer and on a second portion of the strain relaxed silicon germanium alloy buffer layer. A tensily strained silicon material is located on a surface of the p-well region, and a compressively strained germanium-containing material is located on a surface of the n-well region.
