Title: Light-emitting element
Inventor: HAYAKAWA YOSHIYUKI
IPC: H01L21/28
Filed: 1980-08-25
Abstract: PURPOSE:To prevent erroneous recognition and reduce recognition time, in automated assembling of light-emitting elements by means of pattern recognition, by a method wherein a portion or the whole of an electrode branch part, which disturbs recognition of an electrode, is coated with a material having a reflection factor different from that of the electrode. CONSTITUTION:The invention relates to a light-emitting element pellet to be applied to an assembling method automated by means of pattern recognition. The electrode of a light-emitting element comprises bonding pad part 5 or 6 and branch parts 3 or 4 stretching thereto. In addition, the portion which disturbs recognition of the electrode, or a portion or the whole of the branch parts 3 or 4 of the electrode is coated with a material, such as silicon oxide film or the like, which lowers reflection factor. Thereby, pattern recognition is facilitated without damaging electric conductivity of the electrode brahch parts 3 or 4.
