摘要： 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.

摘要翻译： 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。
