发明名称 HIGH VOLTAGE WIRE BOND FREE LEDS
摘要 An LED chip and method of fabricating the same is disclosed that comprises a plurality of sub-LEDs, said sub-LEDs interconnected such that the voltage necessary to drive said sub-LEDs is dependent on the number of said interconnected sub-LEDs and the junction voltage of said sub-LEDs. Each of said interconnected sub-LEDs comprising an n-type semiconductor layer, a p-type semiconductor layer, and an active or quantum well region interposed between the n-type and p-type layers. The monolithic LED chip further comprising a p-electrode having a lead that is accessible from a point on a surface opposite of a primary emission surface of the monolithic LED chip, the p-electrode electrically connected to the p-type layer, and an n-electrode having a lead that is accessible from a point on the surface opposite of the primary emission surface, the n-electrode electrically connected to the n-type layer. These sub-LEDs interconnected by at least a metallization layer on the n-type and p-type layers, which is insulated so that it does not short the sub-LEDs. Further, the LED chip is capable of being electrically coupled for operation without wire bonds.
