Abstract:
The disclosure relates to a high-voltage light-emitting diode (HV LED) and a manufacturing method thereof. A plurality of LED dies connected in series, in parallel, or in series and parallel are formed on a substrate. A side surface of the first semiconductor layer of part of the LED dies is aligned with a side surface of the substrate, such that no space for exposing the substrate is reserved between the LED dies and the edges of the substrate, the ratio of the substrate being covered by the LED dies is increased, that is, light-emitting area per unit area is increased, and the efficiency of light extraction of HV LED is improved.

Claim (Index 1):
A method for manufacturing an HV LED, comprising:\n growing an epitaxial layer on a substrate, wherein the epitaxial layer comprises a first semiconductor layer, a light-emitting layer and a second semiconductor layer stacked in sequence; etching the epitaxial layer using a lithography pattern to form a plurality of light-emitting units, wherein the lithography pattern comprises a plurality of annular patterns, a part of the epitaxial layer corresponding to the annular patterns is partly removed for exposing the first semiconductor layer, the light-emitting units are connected through the first semiconductor layer being exposed, and the epitaxial layer interposed between the annular patterns is partly removed for exposing the substrate; and cutting the first semiconductor layer and the substrate along at least one cutting line for separating the light-emitting units to form a plurality of HV LEDs, wherein the cutting line passes through the first semiconductor layer interposed between the light-emitting units but does not pass through the light-emitting layer or the second semiconductor layer, such that at least one first side surface of the first semiconductor layer becomes part of a cut surface.
