IMPROVED DENSIFICATION FOR FLOWABLE FILMS

摘要

A method of forming a dielectric layer is described. The method first deposits an initially-flowable layer on a substrate. The initially-flowable layer is then densified by exposing the substrate to a high-density plasma (HDP). Essentially no additional material is deposited on the initially-flowable layer, in embodiments, but the impact of the accelerated ionic species serves to condense the layer and increase the etch tolerance of the processed layer.
