Abstract:
1. A method of forming a spatial light modulator for use in a display system, the method comprising: forming a plurality of micromirrors on a first substrate, wherein each micromirror has a fixed portion and a movable portion; providing a second substrate; and hermetically bonding the first substrate and the second substrate together to form an assembly such that the micromirrors are positioned between the substrates; wherein the step of bonding the first substrate and the second substrate further includes: wherein the first sealing ring comprises a first layer of material deposited on the first substrate, and at least one layer of metallic material deposited over the first layer of material; wherein the second sealing ring comprises a first layer of material deposited on the second substrate, and at least one layer of metallic material deposited over the first layer of material; and wherein bonding the first sealing ring to the second sealing ring comprises melting at least one of the metallic layers of the at least one of the first and second sealing rings.
