Abstract
A light-emitting diode chip includes an electrical connection layer is arranged over the light-emitting surface of the light-emitting epitaxial laminated layer, which is not connected with isolation of the dielectric layer. After CMP treatment, the flat surface is plated with a transparent current spreading layer, which reduces horizontal conduction resistance of the transparent current spreading layer and replaces the metal spreading finger for horizontal conduction.
