Patent ID: 8193014

Claim:
A manufacturing method of light-emitting diode, comprising: an attaching-wafer-to-tape step; attaching a first surface of a light-emitting diode epitaxial wafer to an expanding tape, the first surface being opposite to a second surface of the wafer, and the second surface being provided with a plurality of element electrodes, a dicing-wafer-step; dicing the wafer longitudinally and laterally to form a plurality of light-emitting diode elements each of a certain size with a pair of the element electrodes, in a state that each of the light-emitting diode elements is attached to the expanding tape, an expanding-tape step; expanding the expanding tape in a state that each of the diced light-emitting diode elements is attached to the expanding tape, thereby forming a certain space between one another of the diced light-emitting diode elements, a bonding-electrodes step; laying the expanded expanding tape with the plurality of light-emitting diode elements attached over a plurality of pairs of electrodes that are disposed on a printed-circuit board assembly, to electrically dispose each pair of the element electrodes of the plurality of light-emitting diode elements on each pair of the plurality of pairs of electrodes disposed on the printed-circuit board assembly, such that each pair of the element electrodes of the plurality of light-emitting diode elements faces and is bonded to each pair of electrodes disposed on the printed-circuit board assembly; and a removing-tape step; removing the expanding tape from the light-emitting diode elements each bonded to the corresponding pair of the electrodes on the printed-circuit board.
