Patent ID: 6905589

Claim:
A method of making a circuitized substrate, said method comprising: providing a first dielectric layer; securing a first conductive layer to said first dielectric layer; forming at least one first opening within said first dielectric layer, said at least one opening extending through the entire thickness of said first dielectric layer; electroplating a first quantity of conductive material within said at least one first opening using said first conductive layer as a commoning layer for said electroplating so as to not completely fill said at least one first opening; forming a second conductive layer on said first dielectric layer and over said at least one first opening within said first dielectric layer in contact with said first quantity of conductive material within said at least one first opening such that said second conductive layer will have an indentation therein; securing a second dielectric layer to said first dielectric layer; providing at least one second opening within said second dielectric layer in substantial alignment with said at least one first opening in said first dielectric layer; and electroplating a second quantity of conductive material within said at least one second opening in contact with said indentation within said second conductive layer, again using said first conductive layer as a commoning layer for said electroplating of said second quantity of conductive material.
