    摘要: A method for fabricating a vertical light-emitting diode comprises forming a stack including a plurality of epitaxial layers on a patterned first substrate, placing a second substrate on the stack, removing the first substrate to expose the first surface, planarizing a first surface of the stack that was in contact with the patterned first substrate and has a pattern corresponding to a pattern provided on the first substrate to form a planarized second surface, and forming a first electrode in contact with a side of the second substrate that is opposite to the stack, and a second electrode in contact with the second surface of the stack. A roughening step can be performed to form uneven surface portions on a region of the second surface for improving light emission through the second surface of the stack.
