  • Publication number: 20170330998
    Abstract: A method for manufacturing a semiconductor light emitting device package includes forming a light emitting structure including a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer sequentially stacked on a growth substrate, forming a reflective layer on a first surface of the light emitting structure corresponding to a surface of the second conductivity-type semiconductor layer, forming bumps on the first surface, the bumps being electrically connected to the first or second conductivity-type semiconductor layer and protruding from the reflective layer, bonding a support substrate to the bumps on the first surface, removing the growth substrate, bonding a light transmissive substrate coated with a wavelength conversion layer to a second surface of the light emitting structure from which the growth substrate is removed, and removing the support substrate.
