Semiconductor Electroplating Technology

Getting both uniformity and throughput has long been a challenge in gold plating. The fundamental problem is that the gold complex ion moves much slower than copper or other metals; so, small differences in the gold plating fluid velocity at the wafer surface will cause different plating rates across the wafer – and poor uniformity.
