Abstract:
A method of forming a MEM device with an integrated circuit, comprising:providing a semiconductor substrate including a first region and a second region; forming an integrated circuit device on the first region; forming a first insulating layer on the semiconductor substrate; etching the first insulating layer to form a first dielectric layer on the first region and a second dielectric layer on the second region spaced apart from the first dielectric layer; forming a second insulating layer over the semiconductor substrate, the first dielectric layer and the second dielectric layer; etching the second insulating layer to expose the first dielectric layer; forming a third insulating layer over the semiconductor substrate, the second insulating layer and the first dielectric layer; etching the third insulating layer to form a plurality of vias; and forming a metal layer over the semiconductor substrate to fill the vias.
