Claim Text:
1. A device comprising: a capping substrate having a cavity, wherein the capping substrate has a first surface of silicon; and a substrate structure, wherein the substrate structure includes at least one micro-electro mechanical system (MEMS) device, wherein the MEMs device is disposed in the cavity, and wherein the substrate structure includes a layer providing a second surface of silicon; wherein the first surface of silicon interfaces the second surface of silicon to form a fusion bond interface between the substrate structure and the capping substrate wherein the fusion bond interface is between the silicon of the first surface and silicon of the second surface; at least one cavity surrounding at least a portion of the MEMS device; at least one through substrate via (TSV) extending through the capping substrate and the fusion bond interface to contact the substrate structure, wherein the TSV comprises a central region free of conductive material and wherein the TSV provides an electrical connection to an integrated circuit component; and a polymer material in the central region of the TSV.
