    • Disclosed is an AC light emitting diode having an improved transparent electrode structure. The light emitting diode comprises a plurality of light emitting cells formed on a single substrate, each of the light emitting cells having a first conductive type semiconductor layer, a second conductive type semiconductor layer positioned on one region of the first conductive type semiconductor layer, and an active layer interposed between the first and second conductive type semiconductor layers.

    • The present invention provides a method of fabricating a light emitting diode chip having an active layer between an N type semiconductor layer and a P type semiconductor layer. The method comprises the steps of preparing a substrate; laminating the semiconductor layers on the substrate, the semiconductor layers having the active layer between the N type semiconductor layer and the P type semiconductor layer; and forming grooves on the semiconductor layers laminated on the substrate until the substrate is exposed, whereby inclined sidewalls are formed by the grooves in the semiconductor layers divided into a plurality of chips. According to embodiments of the present invention, a sidewall of a semiconductor layer formed on a substrate of a light emitting diode chip is inclined with respect to the substrate, whereby its directional angle is widened as compared with a light emitting diode chip without such inclination. As the directional angle of the light emitting diode chip is wider, when a white light emitting device is fabricated using the light emitting diode chip and a phosphor, light uniformity can be adjusted even though the phosphor is not concentrated at the center of the device. Thus, the overall light emitting efficiency can be enhanced by reducing a light blocking phenomenon caused by the increased amount of the phosphor distributed at the center portion.
    • 本发明提供一种制造在N型半导体层和P型半导体层之间具有有源层的发光二极管芯片的方法。 该方法包括以下步骤:制备基底; 在所述基板上层叠所述半导体层,所述半导体层具有在所述N型半导体层和所述P型半导体层之间的有源层; 以及在层叠在基板上的半导体层上形成凹槽,直到基板被暴露,由此通过划分成多个芯片的半导体层中的凹槽形成倾斜的侧壁。 根据本发明的实施例,形成在发光二极管芯片的基板上的半导体层的侧壁相对于基板倾斜,由此与没有倾斜的发光二极管芯片相比,其方向角度变宽。 随着发光二极管芯片的方位角变宽,当使用发光二极管芯片和荧光体制造白色发光器件时,即使荧光体不集中在器件的中心,也可以调整光均匀性。 因此,通过减少由分散在中心部分的荧光体的量增加引起的遮光现象,可以提高整体发光效率。

    • Disclosed herein is a method of fabricating a light emitting diode. The method comprises preparing a substrate, forming a lower semiconductor layer, an active layer and an upper semiconductor layer on the substrate, forming a photoresist pattern over the upper semiconductor layer such that a sidewall of the photoresist pattern is inclined to an upper surface of the substrate, and sequentially etching the upper semiconductor layer, active layer and lower semiconductor layer using the photoresist pattern as an etching mask. With this structure, since the light emitting diode permits light generated in the active layer to be easily emitted to an outside through the sidewalls of the semiconductor layers, it has improved light emitting efficiency.
    • 本文公开了一种制造发光二极管的方法。 该方法包括在衬底上制备衬底,形成下半导体层,有源层和上半导体层,在上半导体层上形成光致抗蚀剂图案,使得光致抗蚀剂图案的侧壁倾斜于 衬底,并且使用光致抗蚀剂图案作为蚀刻掩模来顺序蚀刻上半导体层,有源层和下半导体层。 利用这种结构,由于发光二极管允许有源层中产生的光通过半导体层的侧壁容易地发射到外部,所以其具有改善的发光效率。
