Method of forming a layer and method of removing reaction by-products
摘要:
In a method of forming a layer, a titanium layer and a titanium nitride layer may be successively formed on a first wafer. By-products adhered to the inside of a chamber during the formation of the titanium nitride layer may be removed from the chamber. Processes of forming the titanium layer, forming the titanium nitride layer, and removing the by-products may be repeated relative to a second wafer.
