Abstract
A method for electroplating a film onto a substrate. Electrical power is supplied to the plating surface through electrical contact made to contact pads on the underside of the substrate. Contact to the contact pads is made within a liquid-tight region. The contact pads are connected to the plating surface through the substrate. Because the contact scheme is provided within a liquid-tight region on the underside of the substrate, the contacts do not erode or become plated, nor do they consume an area of the plating surface.
