Abstract

The invention utilizes introductions of oxygen and hydroxyl to perform an in situ steam generated (ISSG) process to anneal and reoxidize a conventional sidewall oxide layer in a shallow trench isolation. The ISSG annealing process renders the conventional sidewall oxide layer much less stress. The electrical property of the active regions and the isolation quality between the active regions can be assured.
