  • Short channel effect of MOS devices by retrograde well engineering using tilted dopant implantation into recessed source/drain regions
    Publication number: 20080311720
    Abstract: A method of forming a transistor comprising: defining undercut recesses in the substrate at the source/drain regions thereof, the undercut recesses extending beneath the gate electrode; creating a halo implant region beneath the gate electrode between the recesses; and providing raised source/drain structures in the undercut recesses after creating the halo implant region.
    Type: Application

  • Short channel effect of MOS devices by retrograde well engineering using tilted dopant implantation into recessed source/drain regions
    Publication number: 20060065937
    Abstract: A method of providing a halo implant region in a substrate of a MOS device having a gate electrode thereon and defining source/drain regions, a MOS device fabricated according to the above method, and a system comprising the MOS device. The method comprises: defining undercut recesses in the substrate at the source/drain regions thereof, the undercut recesses extending beneath the gate electrode; creating a halo implant region beneath the gate electrode between the recesses; and providing raised source/drain structures in the undercut recesses after creating the halo implant region.
