Abstract:
1. A method of fabricating a spatial light modulator, the method comprising: providing a capping layer having a first surface and an opposing second surface, the first surface defining a plurality of cavities separated by a plurality of standoff sections, each standoff section having a bonding region defined by an entire top surface of each standoff section; applying a glass frit over selected portions of the bonding region of each of the standoff sections, wherein the glass frit including particles embedded therein; B-stage curing the glass frit; placing the capping layer in contact with a CMOS substrate including a plurality of micromirror devices separated by inter-pixel regions, wherein the plurality of cavities of the capping layer are aligned with and overlie the plurality of micromirror devices, and wherein the bonding region of each of the standoff sections is in contact with the CMOS substrate; heating the capping layer and the CMOS substrate to a temperature of about between 300° C. and 350° C.; and bonding the capping layer and the CMOS substrate.
