Abstract:
An integrated circuit (IC) with an integrated microelectromechanical systems (MEMS) structure is provided. In some embodiments, the IC comprises a semiconductor substrate, a back-end-of-line (BEOL) interconnect structure, the integrated MEMS structure, and a cavity. The BEOL interconnect structure is over the semiconductor substrate, and comprises wiring layers stacked in a dielectric region. Further, an upper surface of the BEOL interconnect structure is planar or substantially planar. The integrated MEMS structure overlies and directly contacts the upper surface of the BEOL interconnect structure, and comprises an electrode layer. The cavity is under the upper surface of the BEOL interconnect structure, between the MEMS structure and the BEOL interconnect structure.

Claim (Index 1):
A method for manufacturing an integrated circuit (IC), the method comprising:\n forming a back-end-of-line (BEOL) interconnect structure covering a semiconductor substrate, wherein the BEOL interconnect structure comprises wiring layers stacked in a dielectric region; performing an etch into the dielectric region to form a trench in the dielectric region; forming a sacrificial layer over the dielectric region and filling the trench; performing a planarization into the dielectric region and the sacrificial layer to coplanarize upper surfaces respectively of the dielectric region and the sacrificial layer; forming a microelectromechanical systems (MEMS) structure over the coplanarized upper surfaces respectively of the dielectric region and the sacrificial layer; and performing a cavity etch into the sacrificial layer, through the MEMS structure, to remove the sacrificial layer and to form a cavity in place of the sacrificial layer.
