Abstract :
We have proposed a new MOSFET structure, strained-Si/Si/sub 0.9/Ge/sub 0.1/-on-Insulator (SSGOI) MOSFETs applicable to the sub-100 nm generation. This SSGOI structure was successfully fabricated by the combination of SIMOX technology and the Si re-growth technique. The strained-Si in SSGOI was found to have good crystal quality and very flat interfaces. SSGOI p-MOSFETs exhibited good FET characteristics. It was demonstrated, for the first time, that the hole mobility of the SSGOI p-MOSFETs is higher that of the universal mobility of conventional Si p-MOSFETs.
