    • This invention provides a light-emitting diode chip with high light extraction, which includes a substrate, an epitaxial-layer structure for generating light by electric-optical effect, a transparent reflective layer sandwiched between the substrate and the epitaxial-layer structure, and a pair of electrodes for providing power supply to the epitaxial-layer structure. A bottom surface and top surface of the epitaxial-layer structure are roughened to have a roughness not less than 100 nm root mean square (rms). The light generated by the epitaxial-layer structure is hence effectively extracted out. A transparent reflective layer not more than 5 μm rms is formed as an interface between the substrate and the epitaxial-layer structure. The light toward the substrate is more effectively reflected upward. The light extraction and brightness are thus enhanced. Methods for manufacturing the light-emitting diode chip of the present invention are also provided.
    • 本发明提供一种具有高光提取的发光二极管芯片,其包括基板,通过电光效应产生光的外延层结构,夹在基板和外延层结构之间的透明反射层,以及 一对用于向外延层结构提供电源的电极。 外延层结构的底表面和顶表面被粗糙化以具有不小于100nm均方根(rms)的粗糙度。 因此外延层结构产生的光被有效地抽出。 形成不大于5μm的透明反射层作为衬底和外延层结构之间的界面。 朝向基板的光更有效地向上反射。 因此光提取和亮度增强。 还提供了用于制造本发明的发光二极管芯片的方法。

    • 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.
    • 本发明公开了一种用于制造LED(发光二极管)的方法,其中在透明窗口和LED外延层的前表面之间形成透明导电膜。 透明导电膜可以是金属的氧化物,氮化物或氟化物。 透明导电膜可以通过适当的工艺例如热压力预先形成在透明窗和LED外延层中的一个上,或者两者之中。 通过涉及透明导电膜,由于提供了更大的截面面积,特别是与常规的玻璃或聚合物粘合剂旋涂相比,电流扩散得到改善,电阻降低。 此外,由于诸如GaAs衬底之类的传统的不透明衬底,可以提高发光效率。
