System and method for fabricating light emitting diode (LED) dice with wavelength conversion layers

摘要

A system for fabricating light emitting diode (LED) dice includes a wavelength conversion layer contained on a substrate on an adhesive layer configured to have reduced adhesiveness upon exposure to a physical energy, such as electromagnetic radiation or heat. The system also includes a curing apparatus configured to reduce the adhesiveness of the adhesive layer to facilitate removal of the wavelength conversion layer from the substrate, and an attachment apparatus configured to remove the wavelength conversion layer from the substrate and to attach the wavelength conversion layer to a light emitting diode (LED) die. A method for fabricating light emitting diode (LED) dice includes the steps of exposing the adhesive layer on the substrate to the physical energy to reduce the adhesiveness of the adhesive layer, removing the wavelength conversion layer from the substrate, and attaching the wavelength conversion layer to the light emitting diode (LED) die.
