Abstract
The present disclosure relates to a method of separating a plurality of light-emitting diode (LED) structures from a wafer. According to the method, the LED structures each having a desired size, thickness, and shape can be separated from the wafer, using a commercialized wafer, without damage to the LED structures even without considering the presence or absence of a sacrificial layer and specifically pre-designing a thickness of semiconductor layers in the wafer from the time of wafer manufacturing.
