Abstract: 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.
