Abstract:
A structure and method of forming landing pads for through substrate vias in forming stacked semiconductor components are described. In various embodiments, the current invention describes landing pad structures that includes multiple levels of conductive plates connected by vias such that the electrical connection between a through substrate etch and landing pad is independent of the location of the bottom of the through substrate trench.
