  • Publication number: 20090075445
    Abstract: A transistor may be formed of different layers of silicon germanium, a lowest layer having a graded germanium concentration and upper layers having constant germanium concentrations such that the lowest layer is of the form Si1-xGex. The highest layer may be of the form Si1-yGey on the PMOS side. A source and drain may be formed of epitaxial silicon germanium of the form Si1-zGez on the PMOS side. In some embodiments, x is greater than y and z is greater than x in the PMOS device. Thus, a PMOS device may be formed with both uniaxial compressive stress in the channel direction and in-plane biaxial compressive stress. This combination of stress may result in higher mobility and increased device performance in some cases.

  • Patent number: 7425490
    Abstract: In a metal gate replacement process, a gate electrode stack may be formed of a dielectric covered by a sacrificial metal layer covered by a polysilicon gate electrode. In subsequent processing of the source/drains, high temperature steps may be utilized. The sacrificial metal layer prevents reactions between the polysilicon gate electrode and the underlying high dielectric constant dielectric. As a result, adverse consequences of the reaction between the polysilicon and the high dielectric constant dielectric material can be reduced.

  • Patent number: 7422936
    Abstract: Replacement metal gates may be formed by removing a polysilicon layer from a gate structure. The gate structure may be formed by patterning the polysilicon layer and depositing a spacer layer over the gate structure such that the spacer layer has a first polish rate. The spacer layer is then etched to form a sidewall spacer. An interlayer dielectric is applied over the gate structure with the sidewall spacer. The interlayer dielectric has a second polish rate higher than the first polish rate. A hard mask may also be applied over the gate structure and implanted so that the hard mask may be more readily removed.
