    摘要: A semiconductor structure which includes a semiconductor on insulator (SOI) substrate. The SOI substrate includes a base semiconductor layer; a buried oxide (BOX) layer in contact with the base semiconductor layer; and an SOI layer in contact with the BOX layer. The semiconductor structure further includes a circuit formed with respect to the SOI layer, the circuit including an N type field effect transistor (NFET) having source and drain extensions in the SOI layer and a gate; and a P type field effect transistor (PFET) having source and drain extensions in the SOI layer and a gate. There may also be a well under each of the NFET and PFET. There is a nonzero electrical bias being applied to the SOI substrate. One of the NFET extensions and PFET extensions may be underlapped with respect to the NFET gate or PFET gate, respectively.

    摘要: A method of forming a transistor device includes forming a patterned gate structure over a semiconductor substrate; forming a spacer layer over the semiconductor substrate and patterned gate structure; removing horizontally disposed portions of the spacer layer so as to form a vertical sidewall spacer adjacent the patterned gate structure; and forming a raised source/drain (RSD) structure over the semiconductor substrate and adjacent the vertical sidewall spacer, wherein the RSD structure has a substantially vertical sidewall profile so as to abut the vertical sidewall spacer and produce one of a compressive and a tensile strain on a channel region of the semiconductor substrate below the patterned gate structure.
