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.

Claim (Index 1):
A method of controlling an electroplating cell by monitoring conditions of an electroplating bath, the method comprising:\n (a) reading an initial voltage between a substrate as a first electrode and a second electrode; (b) during electroplating on the substrate in the electroplating cell, repeatedly reading a voltage between the substrate and the second electrode; (c) comparing each of the repeated readings of the voltage to a corresponding expected voltage that drifts from the initial voltage during the electroplating,\n wherein the drift is determined from substrate electroplating operations that produce satisfactory electroplating results; \n (d) determining that one or more of the repeated readings of the voltage deviate from the corresponding expected voltage by a value greater than a threshold deviation; and (e) in response to determining that the one or more of the repeated readings of the voltage deviate from the corresponding expected voltage by a value greater than the threshold deviation, sending a notification and/or suspending operation of the electroplating cell.
