Title: The manufacturing method of flip-chip of the GaN-based light emitting diode
Inventor: CHEN SHING
IPC: H01L33/00
Filed: 1999-07-01
Granted: 2001-03-11
Abstract: The present invention is a manufacturing method of flip-chip of the GaN-based light emitting diode. The GaN blue light emitting diode die is transparent mainly, its positive and negative electrodes are on the same face, and the heights are different. After plating the positive and negative electrodes with tin-lead or gold bumps, since there are only positive and negative electrodes of light emitting diode, so there are only two bumps. If the LED die is reversely pasted to the circuit board in the way of flip-chip, then the unbalanced LED die bumps will slant or fall and cannot be fixed. Therefore, the present invention is to thermally compress the electrode bumps to make it flat after growing bumps on the LED die for fixing the die and package formation. The advantages of packaging the blue light LED in the flip-chip way are that the brightness increases for above 30% approximately (no light-shading effect of the face of conventional electrodes), no gold wire bonding, the volume can be reduced, the yield rate is high, and the quality is stable.
