Claim:
1. A process for depositing a titanium nanolaminate thin film in integrated circuit fabrication comprising: depositing a first titanium material layer comprising nitrogen, oxygen, and/or carbon by at least one cycle of a first deposition process; depositing a second titanium oxide layer by at least one cycle of a second deposition process, wherein the second titanium oxide layer is a different material from the first titanium material; and repeating at least the depositing a first titanium material layer step until a titanium nanolaminate thin film of a desired thickness has been formed, wherein the first titanium material comprises at least one of titanium oxynitride, titanium oxycarbide, titanium nitride, and titanium carbide, and wherein the titanium nanolaminate film comprises multiple alternating layers of the first titanium material layer and the second different titanium oxide layer.
