Method and system for controlling the plasma treatment of a titanium nitride layer formed by a chemical vapor deposition process

摘要

In general, the present invention is directed to a method of forming titanium nitride layers. In one illustrative embodiment, the method comprises forming a layer of titanium nitride by a chemical vapor deposition process, sensing a thickness of the layer of titanium nitride, and providing the sensed thickness of the layer of titanium nitride to a controller. The method further comprises determining at least one parameter of a plasma process to be performed on the layer of titanium nitride based upon the sensed thickness of the layer of titanium nitride and performing the plasma process comprised of the determined at least one parameter on the layer of titanium nitride.
