Abstract
A method and apparatus for depositing a phosphor using transfer molding. The method includes: forming a plurality of light-emitting devices on a wafer and rearranging the light-emitting devices on a carrier substrate according to luminance characteristics of the plurality of light-emitting devices by examining the luminance characteristics of the plurality of light-emitting devices; depositing the phosphor on the rearranged light-emitting devices using transfer molding; and separating the light-emitting devices on the carrier substrate.
