Abstract: A method for fabricating a wafer-level light emitting diode structure is provided. The method includes: providing a substrate, wherein a first semiconductor layer, a light emitting layer, and a second semiconductor layer are sequentially disposed on the substrate; subjecting the first semiconductor layer, the light emitting layer, and the second semiconductor layer with a patterning process to form a first depressed portion, a second depressed portion, a stacked structure disposed on the second depressed portion and a remained first semiconductor layer disposed on the depressed portion, wherein the stacked structure comprises a patterned second semiconductor layer, a patterned emitting layer, and a patterned first semiconductor layer; forming a first electrode on the remained first semiconductor layer of the first depressed portion; and forming a second electrode correspondingly disposed on the patterned second semiconductor layer of the second depressed portion.
