  • Publication number: 20110003422
    Abstract: A method of forming Monolithic CMOS-MEMS hybrid integrated, packaged structures includes the steps of providing: providing at least one semiconductor substrate having a CMOS device area including dielectric layers and metallization layers; applying at least one protective layer overlying the CMOS device area; forming at least one opening on the protective layer and patterning the dielectric and metallization layers to access the semiconductor substrate; forming at least one opening on the semiconductor substrate by etching the dielectric and metallization layers; applying at least one filler layer in the at least one opening on the semiconductor substrate; positioning at least one chip on the filler layer, the chip including a prefabricated front face and a bare backside; applying a first insulating layer covering the front face of the chip providing continuity from the semiconductor substrate to the chip; forming at least one via opening on the insulating layer covering the chip to access at least one contac
