  • Patent number: 6635517
    Abstract: A method of forming a self-aligned gettering region within an SOI substrate is provided. Specifically, the inventive method includes the steps of forming a disposable spacer on each vertical sidewall of a patterned gate stack region, the patterned gate stack region being formed on a top Si-containing layer of an SOI substrate; implanting gettering species into the top Si-containing layer not protected by the disposable spacer and patterned gate stack region; and removing the disposable spacer and annealing the implanted gettering species so as to convert said species into a gettering region.
    Type: Grant
    Filed: August 7, 2001
    Date of Patent: October 21, 2003
    Assignee: International Business Machines Corporation

  • Patent number: 6509241
    Abstract: A process for fabricating an MOS device having a highly-localized halo region includes the formation of a first halo region at a first surface of a silicon substrate, and a second halo region at a second surface of the silicon substrate. The second surface of the silicon substrate is formed by anisotropically etching the first surface of the silicon substrate to remove a portion of the material from the substrate. Both the first and second halo regions are formed by low-energy ion implantation. For the fabrication of an n-channel device, boron is implanted at an energy of no more than about 1 keV. Upon implantation and a subsequent annealing process, the first and second halo regions form a continuous halo region within the semiconductor substrate.

  • Publication number: 20020142526
    Abstract: An SOI circuit configuration effective for minimizing plasma-induced charging damage during fabrication comprises the formation of charge collectors connected to the gate electrode and the semiconductor body, wherein each one of the charge collectors have the same or substantially the same shape and dimension. A connecting structure formed between a device fabricated on SOI substrate and substrate is delayed until the latter stages of processing.

  • Patent number: 6303450
    Abstract: Disclosed is a method comprising providing a silicon surface with an underlying insulator layer, providing a plurality of gates adjacent to source/drain regions, growing source/drains between the said gates such that the source/drains are thicker in regions of larger gate-to-gate pitch, and doping the source/drains with one or more dopants such that the dopants abut the underlying insulator layer.
