Abstract

A method of plating substrates may include placing a substrate in a plating chamber comprising a liquid, and applying a current to the liquid in the plating chamber to deposit a metal on exposed portions of the substrate, where the current may include alternating cycles of a forward plating current and a reverse deplating current. To determine the current characteristics, a model of a substrate may be simulated during the plating process to generate data points that relate characteristics of the plating process and a pattern on the substrate to a range nonuniformity of material formed on the substrate during the plating process. Using information from the data points, values for the forward and reverse currents may be derived and provided to the plating chamber to execute the plating process.
