Color spatial light modulator and method of manufacture
First Claim
1. A process of applying color to at least one selected cell element of a spatial light modulator comprising the steps of:
- a. aligning a substrate containing a color dye adjacent to the spatial light modulator;
b. sublimating the color dye onto at least one cell on the spatial light modulator;
c) generating a pattern of cells in said spatial light modulator; and
d) verifying that only said selected one received said dye.

Abstract
A semiconductor device comprises a plurality of groups of colored cells controllable by electronic circuitry. Each group of colored cells absorb or reflect specified wavelengths of visible light. The electronic signals control the pathways on which each individual cell reflects incident light. A first process for manufacturing such a color spatial light modulator ("SLM") includes aligning a dye-bearing substrate over the spatial light modulator and causing specified portions of the dye to sublimate off of the substrate and condense onto particular cell elements of the spatial light modulator. A second process for producing a colored spatial light modulator places an electrostatic charge in a dye cloud and introduces the charged cloud to the SLM. The dye migrates to those selected cells containing an opposite electrical charge.
