    摘要: A method of forming a semiconductor structure includes providing an active layer and forming adjacent gate structures on the active layer. The gate structures each have sidewalls such that first spacers are formed on the sidewalls. A raised region is epitaxially grown on the active layer between the adjacent gate structures and at least one trench that extends through the raised region and through the active region is formed, whereby the at least one trench separates the raised region into a first raised region corresponding to a first transistor and a second raised region corresponding to a second transistor. The first raised region and second raised region are electrically isolated by the at least one trench.

The functional gate structure includes at least one gate dielectric that is in direct contact with at least the sidewalls of the two fin structures, and at least one gate conductor on the at least one gate dielectric. The sidewall of the gate structure is substantially perpendicular to the upper surface of the substrate surface, wherein the plane defined by the sidewall of the gate structure and a plane defined by an upper surface of the substrate surface intersect at an angle of 90°+/−5°. An epitaxial semiconductor material is in direct contact with the at least two fin structures.

    摘要: An electrical device is provided that includes a substrate having an upper semiconductor layer, a buried dielectric layer and a base semiconductor layer. At least one isolation region is present in the substrate that defines a semiconductor device region and a resistor device region. The semiconductor device region includes a semiconductor device having a back gate structure that is present in the base semiconductor layer. Electrical contact to the back gate structure is provided by doped epitaxial semiconductor pillars that extend through the buried dielectric layer. An epitaxial semiconductor resistor is present in the resistor device region. Undoped epitaxial semiconductor pillars extending from the epitaxial semiconductor resistor to the base semiconductor layer provide a pathway for heat generated by the epitaxial semiconductor resistor to be dissipated to the base semiconductor layer. The undoped and doped epitaxial semiconductor pillars are composed of the same epitaxial semiconductor material.

    摘要: A channel region of a finFET has fins having apexes in a first direction parallel to a surface of a substrate, each fin extending downwardly from the apex, with a gate overlying the apexes and between adjacent fins. A semiconductor stressor region extends in at least the first direction away from the fins to apply a stress to the channel region. Source and drain regions of the finFET can be separated from one another by the channel region, with the source and/or drain at least partly in the semiconductor stressor region. The stressor region includes a first semiconductor region and a second semiconductor region overlying and extending from the first semiconductor region. The second semiconductor region can be more heavily doped than the first semiconductor region, and the first and second semiconductor regions can have opposite conductivity types where at least a portion of the second semiconductor region meets the first semiconductor region.
