Abstract
An integrated monolithic device with a micro-electromechanical system (MEMS) and an integrated circuit (IC) and a method of forming thereof is disclosed. The monolithic device includes a substrate with IC components and a MEMS formed over the IC. A back-end-of-line (BEOL) dielectric having IC interconnect pads in a pad level is formed over the substrate. A MEMS is formed over the BEOL dielectric with the IC interconnect pads. The MEMS includes a MEMS stack having an active MEMS layer and patterned top and bottom MEMS electrodes formed on the top and bottom surfaces of the active MEMS layer. IC MEMS contact vias are formed at least partially through the active MEMS layer. IC MEMS contacts are formed in the IC MEMS contact vias in the active MEMS layer and configured to couple to the IC interconnect pads.
