Abstract:
A silicon-backed light valve package assembly comprising:a matched coefficient of thermal expansion (CTE) substrate;a soft adhesive layer on an upper surface of the matched CTE substrate;a silicon-backed light valve attached to the matched CTE substrate by the soft adhesive layer;a flexible circuit with an opening, the flexible circuit overlaid on the matched CTE substrate so as to expose the silicon-backed light valve through the opening;bonding wires electrically connecting the flexible circuit to the silicon-backed light valve;an encapsulant dam attached to the flexible circuit, the encapsulant dam surrounding the silicon-backed light valve and thereby defining a cavity; anda soft encapsulant layer disposed in the cavity, the soft encapsulant layer at least partially covering the matched CTE substrate, the flexible circuit and the silicon-backed light valve, and completely covering the bonding wires.
