Patent ID: 8872274

Claim:
An integrated circuit device comprising: a donor substrate comprising a silicon substrate, a buried oxide, and a single-crystal silicon-on-insulator layer; and an upside down p-FET disposed on the donor substrate, said upside-down p-FET comprising: self-terminating e-SiGe source and drain regions; a cap of self-aligning silicide/germanide over the e-SiGe source and drain regions; a silicon channel region connecting the e-SiGe source and drain regions; buried oxide above the silicon channel region; a gate controlling a current flow from the e-SiGe source region to the e-SiGe drain region, said gate comprising a thin gate dielectric layer over the silicon-on-insulator layer and a gate conductor line over said thin gate dielectric layer; a first stress liner deposited over the gate and the e-SiGe source and drain regions; and wherein at least a portion of said e-SiGe source and drain regions and the buried oxide are exposed upon removal of the donor substrate.
