METHOD FOR MANUFACTURING LIGHT-EMITTING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18306348 titled 'METHOD FOR MANUFACTURING LIGHT-EMITTING DEVICE

Simplified Explanation

The patent application describes a method for manufacturing a light-emitting device using a support member and first light-emitting elements.

  • The method involves providing first light-emitting elements and a support member with wiring portions.
  • The first light-emitting elements and wiring portions are joined together under specific conditions.
  • The electrical characteristics of each first light-emitting element are evaluated.
  • If any first light-emitting element is found to be defective, it is removed from the support member.
  • The method ensures that only functional first light-emitting elements are used in the final device.


Original Abstract Submitted

A method for manufacturing a light-emitting device includes: providing a plurality of first light-emitting elements, each comprising a joining portion containing gold; providing a support member including: a substrate, and a plurality of wiring portions, each disposed on the substrate and containing gold; joining the joining portions of the first light-emitting elements and corresponding wiring portions of the plurality of wiring portions under a first joining condition; evaluating whether at least one first light-emitting element of the plurality of first light-emitting elements is removable from the support member; evaluating electrical characteristics of each of the plurality of first light-emitting elements; and if the at least one first light-emitting element is removed from the support member, removing from the support member a first light-emitting element determined to be defective in the step of evaluating electrical characteristics of each of the plurality of first light-emitting elements.
