  • Publication number: 20180005841
    Abstract: Technologies for selectively etching oxide and nitride materials on a work piece are described. Such technologies include methods for etching a work piece with a remote plasma that is produced by igniting a plasma gas flow. By controlling the flow rate of various components of the plasma gas flow, plasmas exhibiting desired etching characteristics may be obtained. Such plasmas may be used in single or multistep etching operations, such as recess etching operations that may be used in the production of non-planar microelectronic devices.

  • Publication number: 20130320453
    Abstract: Improving an area scaling on tri-gate transistors is described. An insulating layer is deposited on a fin on a substrate. The insulating layer is recessed to expose the fin. The corner of the fin is rounded off using a noble gas. A gate dielectric layer is deposited on the rounded corner. The radius of curvature of the corner is controllable by adjusting a bias power to the substrate. The radius of curvature of the corner is determined based on the width of the fin to reduce an area scaling of the array.

  • Patent number: 6362034
    Abstract: A method of fabricating a FET having a gate electrode with reduced susceptibility to the carrier depletion effect, includes increasing the amount of n-type dopant in the gate electrode of an n-channel FET. In one embodiment of the present invention, an integrated circuit including NFETs and PFETs is produced with increased n-type doping in the n-channel FET gate electrodes without the use of additional photomasking operations. Prior to polysilicon patterning, a phosphorus doped silica glass (PSG) is deposited over the polysilicon. Subsequent to patterning of the polysilicon, NFET areas are masked, and exposed PFET areas subjected to source/drain extension implant operations. During this sequence, the PSG is removed from PFET areas but remains in the NFET areas. An anneal is performed to drive the phosphorus from the PSG into the NFET gate electrodes. NFET source/drain extensions are formed, and conventional MOSFET processing operations may then be performed to complete the integrated circuit.
