Abstract
The eSiGe layout effect induced by PC-bounded or STI-bounded eSiGe shows impact on device performance and variability increase. For PC-bounded device, performance degradation could be explained by the mobility loss due to reducing eSiGe volume and less stress strength. For STI-bounded device, performance degradation varies, due to strong interaction between eSiGe fill morphology and device overlap capacitance. This observation was confirmed by an eSiGe fill level study. Compared to PC-bounded eSiGe, STI-bounded devices have increase variation due to eSiGe process.
