摘要:
A semiconductor device process for forming a multilayered nitride structure. The nitride is used as either isolation or as part of a dielectric structure. The deposition rate for the nitride is varied to form a multilayered structure with stress accommodation at the interface between sub-layers in the multilayer structure. In addition, the sub-layered structure reduces pin-holes and microcracks in the nitride film and improves the overall uniformity in thickness of the final nitride film.
