Abstract
Apparatus and methods for manufacturing low-resistant substrate contacts in integrated circuits are disclosed. The contacts are low resistive conducting plugs and are located outside the areas of active components. The substrate is connected from the top portion in order to obtain a low resistance. Multiple metal plugs electrically interconnect the substrate of the integrated circuit with the top portion of the integrated circuit.
