The article presents the technical status of A1GaInP Light Emitting Diode (A1GalnP-LED) Thin-Film Reflect substrate (RS) series of chip products in San'an Optoelectronics Co., Ltd. By adopting many advanced technologies and quality control techniques, the epitaxial slices and chips of RS-LED produced by industrialization have good performance and reliability. The RS-LED chips have the high-current and current spreading characteristics by using key processing technologies including Omni directional reflector (ODR), substrate transfer, metallic bonding and surface roughness, and lead to a large rise in brightness. The highest luminance of the red RS-LED ehips can reach 550mcd, and relevant luminous flux can be 3.51m after capsulation. Based on the characteristics of production technique, the key process, the quality control point and key parameter in industrialization process are analyzed, and the effective quality control method in production process is proposed to put into practice.
