ABSTRACT:
A vertical electrode structure of GaN-based light emitting diode discloses an oxide window layer constructing the GaN-based light emitting diode of vertical electrode structure, which effectively decreases the Fresnel reflection loss and total reflection, and further advances the luminous efficiency. Moreover, the further included metal reflecting layer causes the reflection without the selective angle of incidence, thus increasing the coverage of the reflecting angles and further reflecting the light emitted from a light emitting layer effectively. In addition, the invented structure can also advance the function of heat elimination and the electrostatic discharge (ESD) so as to the increase the operating life of the component and to be applicable to the using under the high current driving. Moreover, the vertical electrode structure of the present invention is able to lower down the manufacturing square of the chip and facilitate the post stage of the conventional wire bonding process.
