Patent ID: 7655492

Claim:
A method for making a plurality of spatial light modulators, the method comprising: providing a transparent wafer and a semiconductor wafer; forming a plurality of micromirrors on the semiconductor wafer within each of a plurality of rectangular active areas, wherein the plurality of micromirrors within each rectangular active area form a micromirror array on the semiconductor wafer, and wherein the micromirrors have mirror edges that are neither parallel nor perpendicular to edges of the rectangular active area; bonding the transparent wafer and semiconductor wafer together with a spacer layer therebetween, wherein the spacer layer encircles each rectangular active area individually, so as to form a gap between the wafers in which the micromirrors of each respective rectangular active area are disposed; wherein the bonding is performed by an application of an adhesive, an application of pressure to press the transparent wafer and semiconductor wafer together, and a step of curing the adhesive so as to form a wafer assembly; and singulating the wafer assembly into individual spatial light modulators.
