Abstract
Methods of and apparatuses for monitoring electroplating bath quality in electroplating cells using voltage readings are described herein. Methods involve obtaining real-time voltage readings during an electroplating process and determining whether the voltage readings are within a threshold deviation of an expected voltage reading at a given time.
