Abstract:
A system and method for forming through substrate vias is provided. An embodiment comprises forming an opening in a substrate and lining the opening with a first barrier layer. The opening is filled with a conductive material and a second barrier layer is formed in contact with the conductive material. The first barrier layer is formed with different materials and different methods of formation than the second barrier layer so that the materials and methods may be tuned to maximize their effectiveness within the device.
