Abstract

A MEMS device includes a MEMS substrate with a movable element. Further included is a CMOS substrate with a cavity, the MEMS substrate disposed on top of the CMOS substrate. Additionally, a back cavity is connected to the CMOS substrate, the back cavity being formed at least partially by the cavity in the CMOS substrate and the movable element being acoustically coupled to the back cavity.
