Abstract
Methods and apparatus for manufacturing a semiconductor light-emitting device that emits white light by forming a phosphor layer on an emission surface of the semiconductor light-emitting device at a wafer-level. The method includes: forming a plurality of light-emitting devices on a wafer; thinning the wafer, on which the plurality of light-emitting devices are formed; disposing the thinned wafer on a carrier film; and forming a phosphor layer on an emission surface of the plurality of light-emitting devices on the wafer.
