Electric potential, current density, and deposition rate are controlled to deposit metal alloys, such as tin based solder alloys or magnetic alloys, with minimal variations in the weight ratios of alloying metals at different locations within the deposited metal alloy feature. Alternative embodiments include processes that form metal alloy features wherein the variation in weight ratio of alloying metals within the feature is not necessarily minimized, but is controlled to provide a desired variation.
