ABSTRACT:
The present invention aims to provide a highly reliable light-emitting device capable of simplifying alignment of optical axes of light-emitting element and optical fiber and making optical coupling between them with high efficiency, and a light-emitting device manufacturing method, by which such light-emitting device can be manufactured with high productivity. Since a lens made of radiation sensitive resin is formed directly on a light-emitting element to be located just above a light-emitting surface, it becomes possible to provide a highly reliable light-emitting device capable of allowing the optical axes of the light-emitting element and the optical fiber to be aligned more easily and making optical coupling between them with high efficiency. Further, it becomes possible to provide a manufacturing method capable of manufacturing a highly reliable light-emitting device and comprising the steps of forming a resist layer on a light-emitting element wafer having a plurality of light-emitting surfaces, masking portions of the resist layer just above the light-emitting surfaces, removing the resist layer except the masked portions, and shaping the resist layer into lenses.
