A method for fabricating a MEMS zoom lens device. The device is formed
substantially on a silicon substrate and includes control circuitry
formed on the substrate, multiple actuators having charge areas for
creating electrostatic fields, a flexible support for flexibly coupling a
lens to the substrate, an electrostatic layer coupled to the lens. The
charge areas act in response to the control circuitry to apply an
electrostatic force to the electrostatic layer to move the lens with
respect to the substrate and optical sensors or detectors. In a preferred
embodiment, the flexible support is formed in a serpentine shape from
silicon nitride. A stop support is formed to underlie the flexible
support to prevent damage to the flexible support in a rest (i.e.,
non-zoomed) position.
