Structure and method to make strained FinFET with improved junction capacitance and low leakage
摘要:
A method of forming a semiconductor device that includes forming a gate structure on a fin structure and etching the source and drain region portions of the fin structure to provide a recessed surface. A first semiconductor layer is formed on the recessed surface of the fin structure that is doped to a first conductivity type. A leakage barrier layer is formed on the first semiconductor layer. A second semiconductor layer is formed on the leakage barrier layer. The second semiconductor layer is doped to a second conductivity type.
