Abstract
Methods and apparatus for filling features with cobalt are provided herein. In some embodiments, a method for processing a substrate includes: depositing a first cobalt layer via a chemical vapor deposition (CVD) process atop a substrate and within a feature disposed in the substrate; and at least partially filling the feature with cobalt or cobalt containing material by performing a plasma process in a physical vapor deposition (PVD) chamber having a cobalt target to reflow a portion of the first cobalt layer into the feature. The PVD chamber may be configured to simultaneously deposit cobalt or cobalt containing material within the feature from a cobalt target disposed in the PVD chamber.
