Abstract

We describe the fabrication and testing of deformable membrane mirrors over silicon backplanes using our in-house CMOS processing facilities. The fabrication of dense arrays of electrostatic actuators on the backplane potentially allows fine control of the membrane surface shape than can be produced when using a printed circuit board as the backplane. We presents a range of techniques for fabrication the membrane mirrors in various materials and mating the structure to a silicon backplane. We characterise membrane deflection with electric field for silicon nitride and polymer membranes over a passive silicon backplane consisting of 37 directly-addressed electrode pads configured in a hexagonal array.
