  • Patent number: 9419106
    Abstract: The present description relates to the formation source/drain structures within non-planar transistors, wherein fin spacers are removed from the non-planar transistors in order to form the source/drain structures from the non-planar transistor fins or to replace the non-planar transistor fins with appropriate materials to form the source/drain structures.
    Type: Grant

  • Publication number: 20140339646
    Abstract: The present description relates to the field of fabricating microelectronic devices having non-planar transistors. Embodiments of the present description relate to the doping of fins within non-planar transistors, wherein a conformal blocking material layer, such as a dielectric material, may be used to achieve a substantially uniform doping throughout the non-planar transistor fins.

  • Publication number: 20070126067
    Abstract: Embodiments of the invention provide a device with a reverse-tapered gate electrode and a gate dielectric layer with a length close to that of the gate length. In an embodiment, this may be done by altering portions of a blanket dielectric layer with one or more angled ion implants, then removing the altered portions of the blanket dielectric layer.

  • Publication number: 20070105331
    Abstract: This invention adds to the art of replacement source-drain cMOS transistors. Processes may involve etching a recess in the substrate material using one equipment set, then performing deposition in another. Disclosed is a method to perform the etch and subsequent deposition in the same reactor without atmospheric exposure. In-situ etching of the source-drain recess for replacement source-drain applications provides several advantages over state of the art ex-situ etching. Transistor drive current is improved by: (1) Eliminating contamination of the silicon-epilayer interface when the as-etched surface is exposed to atmosphere and (2) Precise control over the shape of the etch recess. Deposition may be done by a variety of techniques including selective and non-selective methods. In the case of blanket deposition, a measure to avoid amorphous deposition in performance critical regions is also presented.

  • Publication number: 20060131665
    Abstract: A method is described for manufacturing an n-MOS semiconductor transistor. Recesses are formed in a semiconductor substrate adjacent a gate electrode structure. Silicon is embedded in the recesses via a selective epitaxial growth process. The epitaxial silicon is in-situ alloyed with substitutional carbon and in-situ doped with phosphorus. The silicon-carbon alloy generates a uniaxial tensile strain in the channel region between the source and drain, thereby increasing electron channel mobility and the transistor's drive current. The silicon-carbon alloy decreases external resistances by reducing contact resistance between source/drain and silicide regions and by reducing phosphorous diffusivity, thereby permitting closer placement of the transistor's source/drain and channel regions.

  • Publication number: 20050266654
    Abstract: A method includes forming a first and a second semiconductor region which are joined at a semiconductor junction. The first and second semiconductor regions are truncated with an isolation trench, with an end of the semiconductor junction being disposed at the isolation trench. The isolation trench is at least partially filled with an insulation material. A salicide-blocking barrier is formed over a first surface portion of the first semiconductor region proximally disposed relative to the isolation trench. An amorphization implant is implanted in a second surface portion of the first semiconductor region distally disposed relative to the isolation trench. A salicide layer is formed in the amorphization implant.
