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.

Method and apparatus for depositing phosphor on semiconductor-light emitting device

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.

Method and apparatus for manufacturing white light-emitting device

An underfill system for filling gaps between semiconductor chips and substrates is provided. The underfill system comprises a blower for blowing air, an air duct coupled to the blower, the air duct comprising a main duct coupled to the blower and a plurality of sub-ducts each having an outlet being connected to the main duct and an inlet to be located along one side of the semiconductor chip. A filling material from a dispenser fills the gaps by suction due to the pressure difference between the main duct and the sub-duct. Thus, the present invention shortens the filling time of the underfill process and prevents voids or air bubbles of the filling material from forming within the gap.
