Abstract
Methods, apparatus, and systems for depositing copper and other metals are provided. In some implementations, a wafer substrate is provided to an apparatus. The wafer substrate has a surface with field regions and a feature. A copper layer is plated onto the surface of the wafer substrate. The copper layer is annealed to redistribute copper from regions of the wafer substrate to the feature. Implementations of the disclosed methods, apparatus, and systems allow for void-free bottom-up fill of features in a wafer substrate.
