  • Patent number: 11177417
    Abstract: A method for manufacturing a light emitting device includes: providing a wafer that includes, successively from an upper face side, an electrode structure that includes multilayer wiring, a semiconductor layer electrically connected to the electrode structure, and a growth substrate; bonding the wafer to a support substrate; exposing the semiconductor layer by removing the growth substrate from the wafer; separating the semiconductor layer into a plurality of light emitting elements, which comprises forming grooves on a semiconductor layer side surface of the wafer; and forming a phosphor layer having protrusions and recesses at a surface thereof such that the phosphor layer covers surfaces of the light emitting elements, which comprises: forming a coating film on surfaces of the light emitting elements by applying a slurry comprising phosphor particles contained in a solvent, and vaporizing the solvent in the coating film to form the phosphor layer.
