Abstract

The present invention provides a sputter target for the deposition of titanium nitride films. The sputter target has a target face comprising titanium nitride having a density of at least 90% of the theoretical density of 100% pure titanium nitride. The sputter target is prepared by subjecting titanium nitride powder to hot isostatic pressure.
