Abstract
For the first time, tensile and compressively stressed nitride contact liners have been simultaneously incorporated into a high performance CMOS flow. This dual stress liner (DSL) approach results in NFET/PFET effective drive current enhancement of 15%/32% and saturated drive current enhancement of 11%/20%. Significant hole mobility enhancement of 60% is achieved without using SiGe. Inverter ring oscillator delay is reduced by 24% with DSL. Overall yield for the DSL process is comparable to that of a similar technology without DSL. Single and multi-core SOI microprocessors are being manufactured using the DSL process in multiple, high-volume fabrication facilities.
