Abstract:
A high yield method for the fabrication of multi-element, gallium-arsenide-phosphide light emitting diode arrays having square light emitting elements 7903 square microns on 88. 9 micron center suitable for use in electronic/optical printers, is described. The resulting arrays at a current density of 200 A/cm. sup. 2 have 0. 6% power efficiency and a radiant exitance of 3. 8 W cm -2 with less than 2% standard deviation in element to element radiant exitance. The integrated, relatively low cost LED arrays, are particularly suitable for use in electronic/optical printing applications.
