PVD deposition of titanium and titanium nitride layers in the same chamber without use of a collimator or a shutter

PVD deposition of titanium and titanium nitride layers in the same chamber without use of a collimator or a shutter

Ti and TiN layers are formed on an integrated circuit substrate using a titanium target in non-nitrided mode in a hollow cathode magnetron apparatus. Neither a collimator nor a shield is used. Ti and TiN layers are deposited in vias and trenches having aspect ratios up to 5:1.
