    Abstract: A high-performance semiconductor structure and a method of fabricating such a structure are provided. The semiconductor structure includes at least one gate stack (18), e.g., FET, located on an upper surface (14) of a semiconductor substrate (12). The structure further includes a first epitaxy semiconductor material (34) that induces a strain upon a channel (40) of the at least one gate stack. The first epitaxy semiconductor material is located at a footprint of the at least one gate stack substantially within a pair of recessed regions (28) in the substrate which are present on opposite sides of the at least one gate stack. A diffused extension region (38) is located within an upper surface of said first epitaxy semiconductor material in each of the recessed regions. The structure further includes a second epitaxy semiconductor material (36) located on an upper surface of the diffused extension region. The second epitaxy semiconductor material has a higher dopant concentration than the first epitaxy semiconductor material.

    Abstract: A device includes first and second fins defined in a semiconductor substrate and a raised isolation post structure positioned between the first and second fins, wherein an upper surface of the raised isolation post structure is at a level that is approximately equal to or greater than a level corresponding to an upper surface of each of the first and second fins. A first space is defined by a sidewall of the first fin and a first sidewall of the raised isolation post structure, a second space is defined by a sidewall of the second fin and a second sidewall of the raised isolation post structure, and a gate structure is positioned around a portion of each of the first and second fins and around a portion of the raised isolation post structure, wherein at least portions of the gate structure are positioned in the first and second spaces.

    Abstract: A common cut mask is employed to define a gate pattern and a local interconnect pattern so that local interconnect structures and gate structures are formed with zero overlay variation relative to one another. A local interconnect structure may be laterally spaced from a gate structure in a first horizontal direction, and contact another gate structure in a second horizontal direction that is different from the first horizontal direction. Further, a gate structure may be formed to be collinear with a local interconnect structure that adjoins the gate structure. The local interconnect structures and the gate structures are formed by a common damascene processing step so that the top surfaces of the gate structures and the local interconnect structures are coplanar with each other.

    Abstract: SOI CMOS structures having at least one programmable electrically floating backplate are provided. Each electrically floating backplate is individually programmable. Programming can be performed by injecting electrons into each conductive floating backplate. Erasure of the programming can be accomplished by tunneling the electrons out of the floating backplate. At least one of two means can accomplish programming of the electrically floating backgate. The two means comprise Fowler-Nordheim tunneling, and hot electron injection using an SOI pFET. Hot electron injection using pFET can be done at much lower voltage than injection by tunneling electron injection.
