Zusammenfassung:A method of fabricating a device using a sequence of annealing processes is provided. More particularly, a logic NFET device fabricated using a low temperature anneal to eliminate dislocation defects, method of fabricating the NFET device and design structure is shown and described. The method includes forming a stress liner over a gate structure and subjecting the gate structure and stress liner to a low temperature anneal process to form a stacking force in single crystalline silicon near the gate structure as a way to memorized the stress effort. The method further includes stripping the stress liner from the gate structure and performing an activation anneal at high temperature on device.
