Abstract:
1. A method of fabricating an integrated spatial light modulator, the method comprising: providing a first substrate including a bonding surface; processing a device substrate to form at least an electrode layer, the electrode layer including a plurality of electrodes; depositing a first electrically insulating portion of a multi-layer standoff layer on the electrode layer; depositing a second electrically insulating portion of the multi-layer standoff layer on the first electrically insulating portion of the multi-layer standoff layer; forming standoff structures from the multi-layer standoff layer; joining the bonding surface of the first substrate to the standoff structures on the device substrate; thinning the first substrate; patterning the first substrate to form a mask; and forming a plurality of moveable structures from the first substrate, at least one of the plurality of moveable structures aligned with at least one of the plurality of electrodes and adapted to rotate with respect to the standoff structures.
