Abstract
A method of fabricating light emitting diode chips having a phosphor coating layer comprises providing a substrate having a plurality of light emitting diodes formed thereon; forming a conductive bump on at least one of the plurality of light emitting diodes; forming a phosphor coating layer over the substrate and the light emitting diodes; cutting the phosphor coating layer by a point cutter to remove an upper portion of the phosphor coating layer, so as to reduce a thickness of the phosphor coating layer and expose the conductive bump; and forming a plurality of individual light emitting diode chips having the phosphor coating layer by separating the plurality of light emitting diodes.
