The method comprises (a) connecting a source of constant current in a series circuit with the plasma and the semiconductor body, (b) periodically illuminating the metal being anodized with light to produce photocurrents when the metal approaches the completion of anodization, (c) monitoring the voltage across the source of constant current, and (d) terminating the plasma anodization when the monitored voltage ceases to fluctuate as a result of the aforementioned periodic illumination.
