Patent ID: 11183619

Abstract:
A method of manufacturing a light emitting device, including: providing a first structure including: providing a lead frame which includes providing a metal plate including a plurality of pairs of first and second metal parts, each metal part including an upper surface, a lower surface, and an end surface, the end surface of the first metal part and the end surface of the second metal part of each pair are opposite to each other, and a first region including the end surface, and disposing a mask of a resist film on the first region using an electrodeposition technique, disposing a first plated layer containing gold or gold alloy on a second region including the upper surface other than the first region on at least one of the upper surface, the lower surface, and the end surface of each of the first and second metal parts using a plating technique, and removing the resist film, providing a resin molded body molded integrally with the lead frame with parts of a lower surface of the lead frame being exposed, in which the first structure includes an upper surface defining a plurality of recesses each having an upward-facing surface, the first plated layer on the upper surface of the metal part is located at the upward-facing surface of each of the plurality of recesses; providing a second structure, the providing a second structure including; disposing at least one light-emitting element on the upward-facing surface each of the plurality of recesses, disposing a sealing member covering the at least one light-emitting element in each of the plurality of recesses; and separating the second structure into a plurality of discrete light emitting devices.
