Abstract:
A MEMS device and methods of forming are provided. A dielectric layer of a first substrate is patterned to expose conductive features and a bottom layer through the dielectric layer. A first surface of a second substrate is bonded to the dielectric layer and the second substrate is patterned to form a membrane and a movable element. A cap wafer is bonded to the second substrate, where bonding the cap wafer to the second substrate forms a first sealed cavity comprising the movable element and a second sealed cavity that is partially bounded by the membrane. Portions of the cap wafer are removed to expose the second sealed cavity to ambient pressure.

Claim (Index 15):
A micro-electromechanical (MEMS) device, comprising:\n a first substrate, comprising:\n a bottom layer; \n a middle layer over the bottom layer, the middle layer comprising a first opening and a second opening; \n an upper layer over the middle layer, wherein the upper layer comprises a movable element and a membrane, the movable element is disposed over the first opening of the middle layer, and the membrane is disposed over the second opening of the middle layer, and a first cavity having a first pressure is defined by the membrane, the bottom layer, and the middle layer; \n a first through via extending through the upper layer on a first side of the first opening; \n a second through via extending through the upper layer on a second side of the first opening, the first side of the first opening being opposite to the second side of the first opening; \n a third through via extending through the upper layer on a first side of the second opening; and \n a fourth through via extending through the upper layer on a second side of the second opening, the first side of the second opening being opposite to the second side of the second opening; and \n a cap layer, wherein the cap layer is physically coupled to the first substrate by a plurality of bonds, and a first bond of the plurality of bonds is laterally disposed between the second through via and the third through via, and wherein a second cavity is defined by the cap layer and the first substrate, the movable element is disposed in the second cavity, and the second cavity has a second pressure that is different than the first pressure.
