Abstract

A system and method for plating a workpiece are described. In one aspect, an apparatus includes a deposition chamber, a workpiece holder adapted for insertion into and removal from the deposition chamber, a shield with patterns of apertures corresponding to features on the workpiece, a shield holder also adapted for insertion into and removal from the deposition chamber and a positioning mechanism to position the workpiece in the workpiece holder such that the pattern of apertures on the shield will align with the corresponding features on the workpiece when the workpiece holder and shield holder are inserted into the deposition chamber.
