Abstract:
A device and method of preventing corrosion of a copper layer in a PCB is disclosed. A first dielectric is disposed on a substrate. A copper layer is plated in an opening in the first dielectric and, after conditioning the copper layer, a redistribution layer is plated on the copper layer. A solder resist layer is disposed above the copper layer. A solder ball is disposed in an opening in the solder resist layer. The solder ball is in conductive contact with the copper layer and in physical contact with the redistribution layer. A non-conductive carbon layer is disposed on and in contact with the redistribution layer or tsi-diehe solder resist layer. The carbon layer is substantially thinner than the copper layer and acts as a diffusion barrier to moisture for the copper layer.

Claim (Index 11):
A method for protecting a copper layer from, the method comprising:\n spinning on a first dielectric on a substrate comprising at least one of a semiconductor or mold compound; patterning the first dielectric to provide an opening in the first dielectric; plating a copper layer in the opening in the first dielectric; plating a redistribution layer on the copper layer; spinning on and patterning the solder resist layer to provide an opening in the solder resist layer to the redistribution layer; and attaching a solder ball in the opening in the solder resist layer, the solder ball in physical contact with the redistribution layer and in conductive contact with the copper layer, wherein a non-conductive carbon layer that provides a diffusion barrier to moisture for the copper layer is deposited on the substrate, and the non-conductive carbon layer is formed from carbon rather than a carbon compound and.
