Patent ID: 8410487

Claim:
A manufacturing method of a light-emitting diode (LED) chip, comprising the steps of: providing a conductive block, wherein the conductive block comprises: a conductive substrate having a first region and a second region; a first dielectric layer formed on the first region; and a first metal layer formed on the second region and the first dielectric layer; providing an epitaxial block, wherein the epitaxial block comprises: an epitaxial substrate; an epitaxial layer formed on the epitaxial substrate; and a second metal layer formed on a semiconductor side of the epitaxial layer; bonding, wherein the first metal layer is bonded with the second metal layer so that the conductive block and the epitaxial block are bonded together to form a bonded block; removing the epitaxial substrate, wherein the epitaxial substrate is removed from the bonded block so as to form an LED block; making independent LEDs, wherein the LED block is etched so that at least a first LED is formed on the first region and at least a second LED and at least a third LED are formed on the second region; forming a second dielectric layer, wherein the second dielectric layer is formed between the at least a first LED, the at least a second LED, and the at least a third LED; and making electrical connection, wherein a first conductive layer is formed on the second dielectric layer to series-connect each said first LED and each said second LED, and a second conductive layer is formed on the second dielectric layer to parallel-connect each said second LED and each said third LED.
