摘要: A method of forming a nitride film is disclosed. In one embodiment, the method comprises performing an ending film deposition process that differs from the main film deposition process in terms of the flow rates of the reactive and ion source gases, and maintaining acceleration power of a CVD tool during the ending film deposition process. A post deposition process may also be used to remove a denser top layer of nitride, resulting in a nitride film having a consistent density.
