Abstract :
A detailed analysis of the process-induced stress during a standard CMOS manufacturing is presented. Dependence of transistor performance on layout is attributed to the combination of stress induced by shallow trench isolation and source/drain (S/D) silicide. Based on the layout sensitivity, the effect of an individual stress component on NMOS and PMOS is identified. The optimization of transistor layout is proposed to improve the CMOS performance.
