Abstract:
1. A substrate assembly comprising: a lower substrate comprising a plurality of mirror device areas, each mirror device area comprising a mirror array having a rectangular active area and a plurality of deflectable mirrors within the rectangular active area and wherein each area in the plurality of mirror device areas is physically separable from all other areas in the plurality of mirror device areas so that a corresponding mirror array in a separated one of the areas is operable independent of a corresponding mirror area in any of the other areas in the plurality of mirror device areas; wherein the mirrors have a plurality of mirror edges that are neither parallel nor perpendicular to the edges of the active area; an upper light transmissive substrate bonded to the lower substrate with gaps therebetween and covering the plurality of mirror device areas; and an intermediate substrate bonded between the upper and lower substrates and with open areas defining a plurality of cavities at each mirror device location in the gaps.
