Abstract:
A method for manufacturing a light emitting device includes: providing a substrate defining a mounting region having a wiring pattern on an upper face thereof; forming a plurality of bumps arranged in a plurality of columns extending parallel to each other with a distance between adjacent ones of the bumps in one of the columns arranged closest to an outer edge of the mounting region is larger than a distance between adjacent ones of the bumps arranged on an inner side in a plan view, and the bumps include first bumps and second bumps with the first bumps including first large bumps and first small bumps, with all the bumps in the one of the columns arranged closest to the outer edge are the same size; mounting the light emitting element onto the bumps in a flip-chip manner; and forming a cover member.
