Claim Text:
1. A MEMS device comprising: a polymer layer; a substrate disposed on the polymer layer; a MEMS stack disposed on the substrate; a first through opening having a first width and disposed in the polymer layer; a second through opening having a second width and disposed in the substrate such that the second through opening abuts the MEMS stack and the first through opening, wherein a major surface of the polymer layer comprises a contact area for mounting the MEMS device; and a third through opening comprising an empty space disposed in the polymer layer, wherein the first through opening is laterally separated from the third through opening by a region of the polymer layer, wherein the polymer layer, the substrate, the MEMS stack, the first through opening, the second through opening, and the third through opening are part of the MEMS device that is configured to be operational.
