Method of manufacturing light emitting device
First Claim
1. A method of manufacturing a light emitting device, the method comprising:
- mounting a plurality of light emitting elements on a collective substrate;
arranging at least one light transmissive member for each light emitting device on an upper surface of each of the plurality of light emitting elements;
arranging a first protruding member that surrounds the plurality of light emitting elements on an upper surface of the collective substrate;
arranging a second protruding member between the plurality of light emitting elements on the upper surface of the collective substrate;
after the arranging the first protruding member and the second protruding member, forming a cover member that covers an upper end of the second protruding member, the light emitting elements, and a lateral surface of the light transmissive member in a region surrounded by the first protruding member; and
singulating the light emitting devices by dividing the cover member, the second protruding member, and the collective substrate at a portion including the second protruding member;
wherein an upper end of the second protruding member is located in the region surrounded by the first protruding member so as to be lower than an upper end of the first protruding member but higher than the upper surface of each of the light emitting elements, andwherein the second protruding member is harder than the cover member.

Abstract
A method of manufacturing a light emitting device includes: mounting light emitting elements on a collective substrate; arranging a first protruding member surrounding the light emitting elements; arranging a second protruding member between the light emitting elements; forming a cover member covering an upper end of the second protruding member, a lateral surface of each of the light emitting elements in a region surrounded by the first protruding member; and singulating the light emitting devices by cutting the cover member, the second protruding member, and the collective substrate at a portion including the second protruding member. The second protruding member is harder than the cover member. An upper end of the second protruding member is located lower than that of the first protruding member but higher than the upper surface of each of the light emitting elements.

18. A method of manufacturing a light emitting device, the method comprising:
-
mounting light emitting elements on a substrate; arranging light transmissive members on upper surfaces of the light emitting elements, respectively such that gaps separate the light transmissive members, the light transmissive members having lateral surfaces defining gaps; providing an underfill in all of the gaps to cover an upper surface of the substrate, lateral surfaces of the light emitting elements, and the lateral surfaces of the light transmissive members; and arranging a cover member covering an entirety of an upper surface of the underfill between the lateral surfaces of the light transmissive members. - View Dependent Claims (19, 20)
