Eutectic Electrode Structure of Flip-chip LED Chip and Flip-chip LED Chip

摘要

A light emitting diode includes: a light emitting structure including a first semiconductor layer, a light emitting layer, a second semiconductor layer; a first metal layer arranged on at least a portion of the first semiconductor layer and in contact with the first semiconductor layer; and an electrode layer arranged over the light emitting structure, and having a first electrode layer and a second electrode layer. The first electrode layer is electrically coupled to the first and second semiconductor layers; the second electrode layer is configured for bonding with a package substrate, and includes a first and second bonding regions; the first bonding region is electrically coupled to the first semiconductor layer; the second bonding region is electrically coupled to the second semiconductor layer; and the first metal layer is not overlapped with the first bonding region of the second bonding region in a vertical direction.
