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.
