  • Publication number: 20140312420
    Abstract: A plurality of semiconductor fins are formed which extend from a semiconductor material portion that is present atop an insulator layer of a semiconductor-on-insulator substrate. A gate structure and adjacent gate spacers are formed that straddle each semiconductor fin. Portions of each semiconductor fin are left exposed. The exposed portions of the semiconductor fins are then merged by forming an epitaxial semiconductor material from an exposed semiconductor material portion that is not covered by the gate structure and gate spacers.

  • Publication number: 20140070316
    Abstract: A method of forming a semiconductor structure may include forming at least one fin and forming, over a first portion of the at least one fin structure, a gate. Gate spacers may be formed on the sidewalls of the gate, whereby the forming of the spacers creates recessed regions adjacent the sidewalls of the at least one fin. A first epitaxial region is formed that covers both one of the recessed regions and a second portion of the at least one fin, such that the second portion extends outwardly from one of the gate spacers. A first epitaxial layer is formed within the one of the recessed regions by etching the first epitaxial region and the second portion of the at least one fin. A second epitaxial region is formed at a location adjacent one of the spacers and over the first epitaxial layer within one of the recessed regions.

  • Publication number: 20120305940
    Abstract: A method and structure are disclosed for a defect free Si:C source/drain in an NFET device. A wafer is accepted with a primary surface of {100} crystallographic orientation. A recess is formed in the wafer in such manner that the bottom surface and the four sidewall surfaces of the recess are all having {100} crystallographic orientations. A Si:C material is eptaxially grown in the recess, and due to the crystallographic orientations the defect density next to each of the four sidewall surfaces is essentially the same as next to the bottom surface. The epitaxially filled recess is used in the source/drain fabrication of an NFET device. The NFET device is oriented along the <100> crystallographic direction, and has the device channel under a tensile strain due to the defect free Si:C in the source/drain.
