Patent ID: 7349140

Claim:
A spatial light modulator package, the package comprising: a transparent substrate comprising an incident light surface and a face surface; a patterned spacer substrate comprising a spacer face region and a spacer device region, the patterned spacer substrate patterned to form a grid of standoff regions extending from the spacer face region to the spacer device region with a plurality of openings bordered by the grid of standoff regions; a plurality of first alignment marks on the face surface region of the transparent substrate; a plurality of self-limiting alignment marks on the spacer face regions of the standoff regions and aligned with the plurality of first alignment marks; a bond interface formed between the face surface of the transparent substrate and the spacer face regions of the standoff regions; a device substrate comprising a device surface region and a backside surface region; a plurality of second alignment marks on the device substrate; a bond interface formed between the spacer device regions and the device surface region of the device substrate; and a plurality of spatial light modulators coupled to the device surface region of the device substrate, each of the plurality of spatial light modulators aligned with one of the plurality of openings in the spacer substrate.
