    摘要: A method of forming a transistor device includes forming a patterned gate structure over a semiconductor substrate, forming a raised source region over the semiconductor substrate adjacent a source side of the gate structure, and forming silicide contacts on the raised source region, on the patterned gate structure, and on the semiconductor substrate adjacent a drain side of the gate structure. Thereby, a hybrid field effect transistor (FET) structure having a drain side Schottky contact and a raised source side ohmic contact is defined.

    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: An extremely-thin silicon-on-insulator transistor includes a buried oxide layer above a substrate. The buried oxide layer, for example, has a thickness that is less than 50 nm. A silicon layer is above the buried oxide layer. A gate stack is on the silicon layer includes at least a gate dielectric formed on the silicon layer and a gate conductor formed on the gate dielectric. A gate spacer has a first part on the silicon layer and a second part adjacent to the gate stack. A first raised source/drain region and a second raised source/drain region each have a first part that includes a portion of the silicon layer and a second part adjacent to the gate spacer. At least one embedded stressor is formed at least partially within the substrate that imparts a predetermined stress on a silicon channel region formed within the silicon layer.
