Abstract
A method for manufacturing a vertical blue light emitting diode (LED) includes: bonding a growth substrate to a conductive substrate; peeling off the growth substrate; etching the nitride epitaxial layer to remove the buffer layer and the undoped GaN layer and to thin the N-type GaN layer, such that a thickness of a residual nitride epitaxial layer is less than a wavelength of blue light; and forming an N-type electrode on a surface of a residual N-type GaN layer.
