Abstract:
A method of fabricating a micro-electromechanical systems (MEMS) device that is positioned on a wafer substrate that incorporates drive circuitry, the method comprising the steps ofdepositing a first sacrificial layer of an organic material on the wafer substrate, patterning the first sacrificial layer to define openings, depositing a first layer of conductive material on the first sacrificial layer, patterning the first layer of conductive material, depositing a second sacrificial layer of organic material on the first layer of conductive material, patterning the second sacrificial layer, depositing a second layer of conductive material on the second sacrificial layer, patterning the second layer of conductive material, depositing a third sacrificial layer of organic material on the second layer of conductive material, patterning the third sacrificial layer, depositing a structural layer of dielectric material on the third sacrificial layer, patterning the structural layer, and removing the sacrificial layers to release MEMS structures defined by the first and second layers of conductive material and the structural layer.
