High-voltage light emitting diode and fabrication method thereof
A fabrication method of a high-voltage light-emitting diode includes the steps of providing a substrate, and forming a light-emitting epitaxial laminated layer on the substrate; patterning the light-emitting epitaxial laminated layer and fabricating a channel that exposes the substrate surface so as to divide the light-emitting epitaxial laminated layer into a plurality of light-emitting diode units, and the light-emitting diode units at least constitute two rows; fabricating an electrode interconnection line crossing the channel, wherein, two adjacent light-emitting diode units are connected by the electrode interconnection line; fabricating an electrode bonding pad over the outmost light-emitting diode unit of the high-voltage light-emitting diode; and fabricating an insulating protective layer opening at the channel where the potential difference of any two adjacent light-emitting diodes is ≥3 times of the forward voltage of a single light-emitting diode to avoid breakdown of the light-emitting epitaxial laminated layer.
