    摘要: A semiconductor structure in fabrication includes a n-FinFET and p-FinFET. Stress inducing materials such as silicon and silicon germanium are epitaxially grown into naturally diamond-shaped structures atop the silicon fins of the n-FinFET and p-FinFET areas. The diamond structures act as the source, drain and channel between the source and drain. The diamond structures of the channel are selectively separated from the fin while retaining the fin connections of the diamond-shaped growth of the source and the drain. Further fabrication to complete the structure may then proceed.

    摘要: At least one method, apparatus and system disclosed herein fin field effect transistor (finFET) comprising a tall fin having a plurality of epitaxial regions. A first fin of a transistor is formed. The first fin comprising a first portion comprising silicon, a second portion comprising silicon germanium and a third portion comprising silicon. A gate structure above the third portion is formed. An etching process is performed for removing the silicon germanium of the second portion that is not below the gate structure. A first epitaxy region is formed above the first portion. A second epitaxy region is formed vertically aligned with the first epitaxy region and above the second region.

    摘要: A method includes forming a device above an active region defined in a semiconducting substrate. The device includes a plurality of gate structures, a spacer formed adjacent each of the plurality of gate structures, and conductive source/drain contact structures positioned adjacent each of the plurality of gate structures and separated from the associated gate structure by the spacer. A first portion of the conductive source/drain contact structures of a subset of the plurality of gate structures is recessed at a first axial position along a selected gate structure of the plurality of gate structures to define a cavity. A selected source/drain contact structure is not recessed. A first dielectric layer is formed in the cavity. A conductive line contacting the selected source/drain contact structure in the first axial position is formed.
