Abstract
The present invention discloses a light emitting diode (LED) element and a method for fabricating the same, which can promote light extraction efficiency of LED, wherein a substrate is etched to obtain basins with inclined natural crystal planes, and an LED epitaxial structure is selectively formed inside the basin. Thereby, an LED element having several inclines is obtained. Via the inclines, the probability of total internal reflection is reduced, and the light extraction efficiency of LED is promoted.
