    Abstract: A method of creating a semiconductor integrated circuit is disclosed. The method includes forming a first field effect transistor (FET) device and a second FET device on a semiconductor substrate. The method includes epitaxially growing raised source/drain (RSD) structures for the first FET device at a first height. The method includes epitaxially growing raised source/drain (RSD) structures for the second FET device at a second height. The second height is greater than the first height such that a threshold voltage of the second FET device is greater than a threshold voltage of the first FET device.

    Abstract: A method and structure of an embedded stressor in a semiconductor transistor device having a sigma-shaped channel sidewall and a vertical isolation sidewall. The embedded stressor structure is made by a first etch to form a recess in a substrate having a gate and first and second spacers. The second spacers are removed and a second etch creates a step in the recess on a channel sidewall. An anisotropic etch creates facets in the channel sidewall of the recess. Where the facets meet, a vertex is formed. The depth of the vertex is determined by the second etch depth (step depth). The lateral position of the vertex is determined by the thickness of the first spacers. A semiconductor material having a different lattice spacing than the substrate is formed in the recess to achieve the embedded stressor structure.

    Abstract: A lower raised source/drain region is formed on a planar source/drain region of a planar field effect transistor or a surface of a portion of semiconductor fin adjoining a channel region of a fin field effect transistor. At least one contact-level dielectric material layer is formed and planarized, and a contact via hole extending to the lower raised source/drain region is formed in the at least one contact-level dielectric material layer. An upper raised source/drain region is formed on a top surface of the lower raised source/drain region. A metal semiconductor alloy portion and a contact via structure are formed within the contact via hole. Formation of the upper raised source/drain region is limited to a bottom portion of the contact via hole, thereby preventing formation of, and increase of parasitic capacitance by, any additional raised structure in source/drain regions that are not contacted.
