Abstract :
Strained silicon germanium (sSiGe), as channel materials, has received a lot of attention due to its high hole mobility [1]-[4]. sSi/sSiGe/sSOI heterostructure substrate [5]-[8] takes the advantages of the tensile strained Si layer, and thus can increase the critical thickness for pseudomorphically grown SiGe with high Ge concentration. In this work, QW p-MOSFETs [9]-[11] on sSi/sSi0.5Ge0.5/sSOI substrate were characterized and hole mobility was extracted, compared with QW p-MOSFETs on Si/sSi0.5Ge0.5/SOI substrate.
