Abstract: The specification describes a method for processing junction or barrier layer arrays to eliminate leakage defects. The array is anodized under mild electrolytic conditions which reverse bias the diodes. Since the array is reverse biased, anodization occurs selectively at the sites of current leakage and in proportion to the amount of leakage until the leakage is effectively eliminated. Properly formed elements of the array are essentially unaffected.
