Abstract :
A simplified fabrication process for sub-20 nm CMOS double-gate FinFETs is reported. It is a more manufacturable process and has less overlap capacitance compared to the previous FinFET (1999, 2000). Two different patterning approaches-e-beam lithography and spacer lithography-are developed. Selective Ge by LPCVD is utilized to fabricate raised S/D structures which minimize parasitic series resistance and improve drive current.
