    摘要: A strained silicon p-type MOSFET utilizes a strained silicon channel region formed on a silicon germanium substrate. Silicon germanium regions are formed to the silicon germanium layer adjacent to ends of the strained silicon channel region, and shallow source and drain extensions are implanted in the silicon germanium material. The shallow source and drain extensions do not extend into the strained silicon channel region. By forming the source and drain extensions in silicon germanium material rather than in silicon, source and drain extension distortions caused by the enhanced diffusion rate of boron in silicon are avoided.

    摘要: The disclosure describes an exemplary method of measuring gate capacitance to determine electrical thickness of a gate dielectric located in a gate structure of a metal oxide semiconductor field effect transistor (MOSFET). This method can include connecting a meter to an integrated circuit gate structure and an active region located proximate the integrated circuit gate structure, applying forward body bias to the transistor to reduce the electrical field of the transistor at a gate inversion measuring point; and measuring capacitance from the meter while the transistor receives the forward body bias.

    摘要: An n-type MOSFET (NMOS) is implemented on a substrate having an epitaxial layer of strained silicon formed on a layer of silicon germanium. The MOSFET includes first halo regions formed in the strained silicon layer that extent toward the channel region beyond the ends of shallow source and drain extensions. Second halo regions formed in the underlying silicon germanium layer extend toward the channel region beyond the ends of the shallow source and drain extensions and extend deeper into the silicon germanium layer than the shallow source and drain extensions. The p-type dopant of the first and second halo regions slows the high rate of diffusion of the n-type dopant of the shallow source and drain extensions through the silicon germanium toward the channel region. By counteracting the increased diffusion rate of the n-type dopant in this manner, the shallow source and drain extension profiles are maintained and the risk of degradation by short channel effects is reduced.

    摘要: A semiconductor device includes a semiconductor fin formed on an insulator and sidewall spacers formed adjacent the sides of the fin. A gate material layer is formed over the fin and the sidewall spacers and etched to form a gate. The presence of the sidewall spacers causes a topology of the gate material layer to smoothly transition over the fin and the first and second sidewall spacers.
