Abstract:
A stacked semiconductor structure includes a first substrate. A multilayer interconnect is disposed over the first substrate. Metal sections are disposed over the multilayer interconnect. First bonding features are over the metal sections. A second substrate has a front surface. A cavity extends from the front surface into a depth D in the second substrate. A movable structure is disposed over the front surface of the second substrate and suspending over the cavity. The movable structure includes a dielectric membrane, metal units over the dielectric membrane and a cap dielectric layer over the metal units. Second bonding features are over the cap dielectric layer and bonded to the first bonding features. The second bonding features extend through the cap dielectric layer and electrically coupled to the metal units.

Claim (Index 17):
A method, comprising:\n forming a redistribution structure over a first substrate; forming first metal segments and second metal segments over the redistribution structure, wherein one or more of the first metal segments and second metal segments are electrically coupled to the redistribution structure; disposing a first dielectric layer over the first metal segments and second metal segments; removing a portion of the first dielectric layer to expose the first metal segments to expose portions of the second metal segments and to form a dielectric bump on the second metal segments in a first cavity area of the first substrate; disposing a second dielectric layer over the first dielectric layer, first metal segments, and the exposed portions of the second metal segments; forming an opening in the second dielectric layer, exposing a portion of the second metal segments; forming first bonding features in the opening, the first bonding features electrically coupled to the second metal segments; bonding the first bonding features to corresponding second bonding features of a micro-electro-mechanical system (MEMS) structure, the bonding sealing a movable portion of the MEMS structure in a cavity disposed between the first metal segments and MEMS structure, the movable portion being aligned with the first metal segments.
