Abstract:
A barrier layer is formed over electrically conductive contact pads on a substrate such as a wafer. A photoresist layer is applied over the barrier layer, and openings in the photoresist layer are filled with solder to form solder bumps. The barrier layer may be removed from within the openings prior to filling the openings with solder. The process is applicable to fine pitch architectures and chip size packaging substrates. The photoresist layer and portions of the barrier layer outside of the openings are removed following solder fill.

Claim (Index 19):
The method of  claim 1 , wherein the solder has a height that is level with a top surface of the photoresist layer.
