    • 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.

    • A method for fabricating GaN-based LED is provided. The method first forms a first contact spreading metallic layer on top of the texturing surface of the p-type ohmic contact layer. The method then forms a second and a third contact spreading metallic layers on top of the first contact spreading layer. The p-type transparent metallic conductive layer composed of the three contact spreading metallic layers, after undergoing an alloying process within an oxygenic or nitrogenous environment under a high temperature, would have a superior conductivity. The p-type transparent metallic conductive layer could enhance the lateral contact uniformity between the p-type metallic electrode and the p-type ohmic contact layer, so as to avoid the localized light emission resulted from the uneven distribution of the second contact spreading metallic layer within the third contact spreading metallic layer. The GaN-based LED's working voltage and external quantum efficiency are also significantly improved.
