Abstract:
An integrated circuit and mirror device, the device comprising:a first substrate comprising a plurality of electrode groups, each of the groups comprising a plurality of electrodes; a mirror array formed on a second substrate, each of the mirrors on the array having a mirror surface being able to pivot about a point in space, each of the mirrors having a backside surface operably coupled to one of the electrode groups; a bonding layer mechanically coupling the first substrate to the second substrate, whereupon the backside surface of each mirror faces one of the electrode groups; a drive circuitry coupled to each electrode groups, the drive circuitry being configured to apply a voltage to any one of the electrodes in each of the electrode groups, the drive circuitry being disposed in the first substrate and being adapted to pivot each of the mirror faces about the point in space; and an input/output circuit coupled to each of the electrodes.
