Abstract:
A method of fabricating a micro-electromechanical device, the device comprising a single semiconductor substrate having an insulating layer thereon, the method comprising:disposing a conductor on the insulating layer, providing a polysilicon membrane, the membrane being formed by surface micromachining through the deposition and patterning of a polysilicon layer, the membrane comprising a membrane top and membrane sides, the membrane sides supporting the membrane above the conductor and the insulating layer, the membrane being conductive; the membrane being deflectable and arranged to move towards the conductor under electrostatic attraction in response to a power source connected to the conductor and the membrane; wherein the conductor and the membrane are formed by thin film deposition; and wherein the membrane comprises an actuator and the micro-electromechanical device comprises an actuator device.
