Abstract:
1. A method comprising: forming a first layer having a first die on a base substrate in a package; forming a next layer having a next die on the first layer, the dice having copper plated interconnects for die interconnection, wherein the copper plated interconnects are directly attached to the die; interconnecting the dice using a substantially vertical interconnecting column comprising copper plating to connect the copper plated interconnects; forming a first photo-resist layer of a dielectric material on the next layer; attaching a final die to the first photo-resist layer; forming a second photo-resist layer on the final die and the first photo-resist layer; forming copper on the second photo-resist layer for substrate and die interconnection; and forming a third photo-resist layer on the second photo-resist layer having at least an open pad connection for interconnection with a component or a board.
