Abstract: A method is performed for the fabrication of LED and its structure. The LED is capable of emitting uniform white light and includes a substrate, an LED die, a holding frame and fluorescent substance where the holding frame is of hollow shape. The LED contains a die emitting blue light, and the fluorescent substance is a yellow phosphor. As the LED die is mounted on the substrate, the holding frame is seated on the die, and a bond wiring is performed. The holding frame is filled with the fluorescent substance in a uniform distribution on the die to form a layer of fluorescence. Finally the structure of the LED is accomplished as the packaging is completed.
