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 1):
A micro-electromechanical (MEMS) device, comprising:\n a first substrate comprising:\n a bottom layer; \n a dielectric layer overlying the bottom layer; \n an upper layer overlying the dielectric layer, the upper layer comprising a membrane and a movable element; \n a first cavity disposed in the dielectric layer, the first cavity partially bounded by the bottom layer, partially bounded by the dielectric layer, and partially bounded by the membrane, wherein a first conductive feature is disposed in the first cavity on the bottom layer, and the first cavity has a first pressure; and \n a second conductive feature disposed on the bottom layer in an opening of the dielectric layer, wherein the movable element is positioned over the second conductive feature; and \n a plurality of bonds disposed on a surface of the upper layer, wherein the membrane is directly physically connected to a portion of the upper layer on which a first bond of the plurality of bonds is disposed, wherein the first bond is a closest bond to the membrane; and a cap layer bonded to the first substrate using the plurality of bonds, wherein the cap layer and the first substrate define a second cavity having a second pressure and a third cavity having an ambient pressure, the third cavity being partially bounded by the membrane, and wherein the second cavity extends through the upper layer of the first substrate to the bottom layer, the movable element is disposed in the second cavity, and the second pressure is different than the first pressure.
