Abstract:
A method of manufacturing a plurality of light emitting elements, the method includes: providing a semiconductor wafer; dividing the p-side nitride semiconductor layer into a plurality of demarcated element regions; forming a protective layer on regions including an outer periphery of an upper surface of the p-side nitride semiconductor layer of each of the plurality of demarcated element regions and exposed side surfaces in the semiconductor structure that are formed by the selectively removing the portion of the p-side nitride semiconductor layer; reducing a resistance of regions of the p-side nitride semiconductor layer; and dividing the semiconductor wafer into a plurality of light emitting elements.

Claim (Index 1):
A method of manufacturing a plurality of light emitting elements, the method comprising:\n providing a semiconductor wafer comprising:\n a substrate, and \n a semiconductor structure comprising:\n an n-side nitride semiconductor layer containing an n-type dopant and located above the substrate, and \n a p-side nitride semiconductor layer containing a p-type dopant and located above the n-side nitride semiconductor layer; \n \n selectively removing a portion of the semiconductor structure from an upper surface side of the semiconductor structure to expose the n-side nitride semiconductor layer, in regions that include borders of areas to become the plurality of light emitting elements in a top view, so as to divide the p-side nitride semiconductor layer into a plurality of demarcated element regions; disposing a protective layer on regions including an outer periphery of an upper surface of the p-side nitride semiconductor layer of each of the plurality of demarcated element regions and exposed lateral surfaces of the semiconductor structure that are formed by selectively removing the portion of the semiconductor structure; annealing the semiconductor wafer to reduce a resistance of regions of the p-side nitride semiconductor layer where the protective layer is not provided in a top view; irradiating laser light in an interior region of the substrate so as to form modified regions in the substrate; and dividing the semiconductor wafer by using the modified regions to obtain the plurality of light emitting elements.
