Title:
COMPOSITE SEMICONDUCTOR FULL-COLOR LIGHT EMITTING ELEMENT AND LIGHT EMITTING DEVICE USING IT
Document Type and Number:
Japanese Patent JP3893735
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable a composite semiconductor full-color light emitting element to emit light rays of different colors by making the electrical connection of the element easier and improving the breakdown voltage against impressed high voltages of static electricity, surge, etc.
SOLUTION: A composite semiconductor full-color light emitting element is constituted by mounting semiconductor light emitting elements 5, 6, and 7 for red, green, and blue in continuity on an Si diode 3 for static electricity protection connected in continuity to a lead frame or substrate. The light emitting elements 6 and 7 for green and blue are used as GaN-containing flip chip light emitting elements and, at the same time, micro-bumps 6d and 6e are formed on the n- and p-side electrodes of the elements 6 and 7 and conducted to the polarity opposite to that of the diode 3.
