  • Publication number: 20110156110
    Abstract: Methods of forming integrated circuit devices include forming a field effect transistor having a gate electrode, a sacrificial spacer on a sidewall of the gate electrode and silicided source/drain regions. The sacrificial spacer is used as an implantation mask when forming highly doped portions of the source/drain regions. The sacrificial spacer is then removed from the sidewall of the gate electrode. A stress-inducing electrically insulating layer, which is configured to induce a net tensile stress (for NMOS transistors) or compressive stress (for PMOS transistors) in a channel region of the field effect transistor, is then formed on the sidewall of the gate electrode.

  • Patent number: 7902082
    Abstract: Methods of forming integrated circuit devices include forming a field effect transistor having a gate electrode, sacrificial nitride spacers on opposing sidewalls of the gate electrode and source/drain regions, which are self-aligned to the sacrificial nitride spacers, on a semiconductor substrate. The sacrificial nitride spacers are selectively removed using a diluted hydrofluoric acid solution having a nitride-to-oxide etching selectivity in excess of one. In order to increase charge carrier mobility within a channel of the field effect transistor, a stress-inducing electrically insulating layer is formed on opposing sidewalls of the gate electrode. This insulating layer is configured to induce a net tensile stress (NMOS) or compressive stress (PMOS) in the channel.

  • Patent number: 7863201
    Abstract: Methods of forming integrated circuit devices according to embodiments of the present invention include forming a PMOS transistor having P-type source and drain regions, in a semiconductor substrate, and then forming a diffusion barrier layer on the source and drain regions. A silicon nitride layer is deposited on at least portions of the diffusion barrier layer that extend opposite the source and drain regions. Hydrogen is removed from the deposited silicon nitride layer by exposing the silicon nitride layer to ultraviolet (UV) radiation. This removal of hydrogen may operate to increase a tensile stress in a channel region of the field effect transistor. This UV radiation step may be followed by patterning the first and second silicon nitride layers to expose the source and drain regions and then forming silicide contact layers directly on the exposed source and drain regions.
