    Abstract: A method of providing a CMOS-MEMS structure is disclosed. The method comprises patterning a first top metal on a MEMS actuator substrate and a second top metal on a CMOS substrate. Each of the MEMS actuator substrate and the CMOS substrate include an oxide layer thereon. The method includes etching each of the oxide layers on the MEMS actuator substrate and the base substrate, utilizing a first bonding step to bond the first patterned top metal of the MEMS actuator substrate to the second patterned top metal of the base substrate. Finally the method includes etching an actuator layer into the MEMS actuator substrate and utilizing a second bonding step to bond the MEMS actuator substrate to a MEMS handle substrate.

    Abstract: A method for manufacturing a MEMS double-layer suspension microstructure comprises steps of: forming a first film body (310) on a substrate (100), and a cantilever beam (320) connected to the substrate (100) and the first film body (310); forming a sacrificial layer (400) on the first film body (310) and the cantilever beam (320); patterning the sacrificial layer (400) located on the first film body (310) to manufacture a recessed portion (410) used for forming a support structure (520), the bottom of the recessed portion (410) being exposed of the first film body (310); depositing a dielectric layer (500) on the sacrificial layer (400); patterning the dielectric layer (500) to manufacture a second film body (510) and the support structure (520), the support structure (520) being connected to the first film body (310) and the second film body (510); and removing the sacrificial layer (400) to obtain the MEMS double-layer suspension microstructure.
