Abstract:
1. A method of forming an interconnect module by a process comprising the steps of: providing at least one sheet of dielectric, at least a bottom surface of the at least one sheet of dielectric being covered with a conductive bottom layer; forming a first via through the at least one sheet of dielectric, said first via extending from a top surface o the at least one sheet of dielectric to a top surface of the bottom layer; plating the first via with a first metal to form a first vertical member that comprises the first metal, said first vertical member extending from inside the first via to outside the first via; removing an excess amount of the first metal from outside the first via, resulting in a top surface of the first vertical member being coplanar with the top surface of the at least one dielectric sheet; and before the step of plating the first via with the first metal, plating a second metal within the first via and on the top surface of the bottom layer such that the second metal is in direct mechanical contact with the bottom layer.
