ABSTRACT:
A PVD sputter system having a nonplanar target surface is disclosed. The configuration of the nonplanar target surface is adjusted to provide improved uniformity in deposition film thickness and step coverage at the peripheral boundary regions of the substrate. Emission-inducing power is distributed independently to different portions of the nonplanar target surface so as to modify the deposition profile according to substrate size and other factors.
