Claim 17:
18. An apparatus, comprising:
a substrate having a substrate surface, the substrate having a cavity extending into the substrate surface, trenches extending into the substrate surface, the trenches spaced from the cavity;
a die comprising a spatial light modulator, the die having an active surface and a backside surface opposite the active surface, the die having bond pads on the active surface and having the backside surface mounted in the cavity;
an optically transmissive window mounted over at least a portion of the active surface of the die;
bond wires coupling the bond pads to conductive material on the substrate surface, the conductive material spaced from the cavity, the conductive material on the substrate surface between the cavity and the trenches; and
dielectric material over the bond wires, the conductive material, and the bond pads, the dielectric material extending from the die to an edge of one of the trenches.
