Abstract
For the first time, we demonstrate stressor contact etch stop liner (sCESL) modulation of parasitics/external resistance in nonplanar devices. We report 17% saturation drive current enhancement in underlap doped cMOS FinFETs attributed to simultaneous lowering of RS/D via biaxial S/D stress and μo increase via effective uniaxial channel stress. Our observations imply that biaxial strain engineering for reduction of RS/D offers a significant opportunity to realize non-planar CMOSFET performance metrics for the 22nm node and beyond.
