Integrated Color Imaging Array and Method of Manufacture

An application of the xerographic process is employed in fabricating a tricolor, semiconductor optical detector.

The improvement in the method for fabricating an integrated color imaging array, commences with the deposition of a glass layer 4 on a semiconductor substrate 2 having a plurality of photocells 6 of conventional design, formed in the surface of the substrate 2. A first pattern of localized regions of electrostatic charge 8 are deposited on the photocells 6, by a scanning electron beam, as is shown in Fig. 1.

Fig. 2 shows the next step of employing the spraying nozzle 10 to spray a very fine grained, positively charged xerographic toner powder having a first primary color, optical absorption characteristic, over the surface of the glass layer
4. The spray of particles 12 will deposit in aggregations 14 at the locations 8 of the electrostatic charge. The colored plastic toner 12 will consist of plastic toner particles approximately one micrometer in diameter, which are capable of cohesive fusion upon being exposed to an elevated temperature, in a manner similar to conventional xerographic toners.

The next step consists of elevating the temperature of the aggregates 14 in Fig. 2 to fuse the same, forming a first plurality of optical filters for selectively passing a first primary color to the first selected plurality of photocells 6, as is shown in Fig. 3.

Next, the steps of depositing a negative el...
