Abstract

A MEMS device has a substrate with a structure surface and an opposing exterior surface, microstructure formed on the structure surface of the substrate, and a cap coupled with the substrate to form a hermetically sealed interior chamber containing the microstructure. The substrate forms a trench extending from, and being open to, the opposing exterior surface to produce a sensor region and a second region. Specifically, the second region is radially outward of the sensor region. The MEMS device also has a spring integrally formed at least in part within the trench to mechanically connect the sensor region and the second region, and other structure integral with the substrate. The spring or the other structure at least in part hermetically seal the interior chamber.
