Abstract
The present invention discloses a method for producing an LED (light emitting diode), in which a transparent conductive film is formed between a transparent window and the front surface of a LED epitaxial layer. The transparent conductive film can be oxides, nitrides or fluorides of metals. The transparent conductive film can be preliminarily formed on one of the transparent window and the LED epitaxial layer or both of them by a suitable process, for example, thermal pressure. By involving the transparent conductive film, current spreading is improved and resistance is reduced because of larger cross section areas provided, particularly compared with the conventional spin on glass or polymer adhesives. Additionally, light-emitting efficiency can be improved since the conventional opaque substrate, such as a GaAs substrate.
