Methods and apparatus for dynamically treating atomic layer deposition films in physical vapor deposition chambers

Atomic layer deposition (ALD) processes are combined with physical vapor deposition (PVD) processes in a low pressure environment to produce a high quality barrier film. The initial barrier film is deposited on a substrate using ALD processes and then moved to a PVD chamber to treat the barrier film to increase the barrier film's density and purity, decreasing the barrier film's resistivity. A dual source of materials is sputtered onto the substrate to provide doping while a gas is simultaneously used to etch the substrate to release nitrogen. At least one source of material is positioned to provide doping at an acute angle to the surface of the substrate while supplied with DC power and RF power at a first RF power frequency. The substrate is biased using RF power at a second RF power frequency.

Thus, a target and/or coil is provided that has a uniform and fine structure, makes plasma stable, and allows a film to be formed with excellent uniformity. A method of producing the target and/or the coil is also provided.

In a plasma enhanced physical vapor deposition of a material onto workpiece, a metal target faces the workpiece across a target-to-workpiece gap less than a diameter of the workpiece. A carrier gas is introduced into the chamber and gas pressure in the chamber is maintained above a threshold pressure at which mean free path is less than 5% of the gap. RF plasma source power from a VHF generator is applied to the target to generate a capacitively coupled plasma at the target, the VHF generator having a frequency exceeding 30 MHz. The plasma is extended across the gap to the workpiece by providing through the workpiece a first VHF ground return path at the frequency of the VHF generator.
