Classification: CPC B  G  H | IPC B  H

Claim 0:
1. A microelectromechanical system (MEMS) device, comprising:
a metallization structure disposed over a first semiconductor substrate, wherein the metallization structure comprises a plurality of conductive features embedded in a dielectric structure, wherein the dielectric structure has a first portion disposed over a second portion, and wherein a first sidewall of the first portion of the dielectric structure is laterally spaced from a first sidewall of the second portion of the dielectric structure;
a cavity disposed in the metallization structure, wherein the cavity is disposed laterally between the first sidewall of the first portion of the dielectric structure and a second sidewall of the first portion of the dielectric structure opposite the first sidewall of the first portion of the dielectric structure; and
a second semiconductor substrate disposed over the metallization structure, wherein the second semiconductor substrate comprises a movable element disposed within the cavity.
