Method and system for controlling a substrate position in an electrochemical process

摘要

By using signals from an electric drive assembly of an electroplating tool, the operating position of the substrate surface to be plated may be determined in an automated fashion wherein, based on a reference position, the meniscus of the electrolyte and/or any appropriate operating position may be determined. Consequently, accuracy and throughput may be enhanced compared to conventional manual or semi-automatic adjustment procedures.
