Abstract:
1. A method for fabricating a photoelectric device of Al x In y Ga 1-x-y N semiconductor, comprising steps of: forming a first Al forming a patterned dielectric mask layer on the first Al etching unmasked portion of the first Al removing the dielectric mask layer thereby patterning the first Al forming a second Al forming an N-type semiconductor layer, an active layer, and a P-type semiconductor layer on the second Al forming a metal mirror layer on the P-type semiconductor layer, whereby the N-type semiconductor layer, the active layer, and the P-type semiconductor layer are located between the second Al forming a copper-tungsten conductive layer on the metal mirror layer; disposing an etching protection layer on the copper-tungsten conductive layer and the metal mirror layer; releasing the temporary substrate by removing the first Al removing remnants of the first Al wherein a material of the temporary substrate comprises one of zinc oxide and magnesium oxide; wherein the patterned dielectric mask layer is a photoresist layer; and wherein 0<x<1 and 0<y<1.
