Deposition of alloys by electroplating, varies conditions under computer control to achieve homogenous deposit or deposit exhibiting concentration gradient in its thickness

摘要

During plating, parameters are varied in accordance with time, using programmed control. A multidimensional characteristic diagram is employed. An alloy of given composition is deposited. It is either homogeneous or has a concentration gradient over the layer thickness, An Independent claim is included for the corresponding electroplating plant.
