Abstract
A method of forming a light-emitting diode (LED) device is provided. The method includes steps of providing a first substrate, forming an LED structure on the first substrate, forming a porous layer on the first substrate after forming the LED structure, forming a conductive substrate on the LED structure, and separating the LED structure from the first substrate along the porous layer. The substrate has a doped layer. The forming of the porous layer includes a step of converting the dopes layer to the porous layer.
