Abstract:
1. A method of fabricating a micro-electromechanical actuating mechanism on a wafer substrate, the method comprising the steps of: carrying out a CMOS fabrication process on the wafer to form transistor control and drive circuitry; depositing sacrificial material on the transistor control and drive circuitry; etching the sacrificial material to provide connection access to the drive circuitry; carrying out a MEMS fabrication process on the layer of sacrificial material to form a micro-electromechanical actuator connected to the drive circuitry and responsive to electrical signals from the drive circuitry; and removing the sacrificial material to free the micro-electromechanical actuator, wherein the steps of carrying out the CMOS and MEMS fabrication processes are such that the transistor circuitry is interposed between the actuator and the wafer substrate.
