Example Embodiment
[0050] (Embodiment)
[0051] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In addition, the embodiments described below have shown a specific example of the present invention. Thus, the value, shape, material, constituent element, constituent element of the following embodiments, and the sequential sequence of the steps and the steps and the steps of the step are not intended to limit the invention.
[0052] Further, each figure is a schematic, and it is not necessarily strictly illustrated. Thus, the proportional rule in each figure is not necessarily consistent. Further, in each of the drawings, the same indicia, omit or simplify repetition is given to the substantially the same structure.
Example Embodiment
[0053] (Embodiment 1)
[0054] [Semiconductor LED]
[0055] First, use figure 1 The structure of the semiconductor light-emitting element 1 of the first embodiment will be described. exist figure 1 In, (a) is a plan view of the semiconductor light-emitting element 1 of Embodiment 1, (b) is a vertical cross-sectional view of the semiconductor light-emitting element 1 of the A-A line of (a), (c) is (c) B-B of (b) The horizontal cross-sectional view of the semiconductor light-emitting element 1 of the line. In addition, figure 1 In order to easily understand the positional relationship of each component, a shadow is also applied in the plan view of (a). This is also the same in the following figures.
[0056] likefigure 1 As shown, the semiconductor light-emitting element 1 of Embodiment 1 has a semiconductor laminated structure 10 and an N-side electrode 20 and a P-side electrode 30 disposed at semiconductor laminated structural 10. In the present embodiment, the semiconductor light...
Example Embodiment
[0216] (Embodiment 2)
[0217] Then Figure 22 The semiconductor light-emitting element 1H of the second embodiment will be described. exist Figure 22 In the middle, (a) is a plan view of the semiconductor light-emitting element 1H of the second embodiment, (b) is a vertical cross-sectional view of the semiconductor light-emitting element 1H of the A-A line of (a), (c) is B-B of (b) The horizontal cross-sectional view of the semiconductor light-emitting element 1H of the line.
[0218] The semiconductor light-emitting element 1H of the present embodiment is different from the semiconductor light-emitting element 1 of the first embodiment, and the structure of the N-side electrode is different.
[0219] Specifically, in the semiconductor light-emitting element 1 of the first embodiment, the N-side electrode layer 21 of the n-side electrode 20 has the first metal layer 21a, the second metal layer 21b, and the third metal layer 21c, but in the present embodiment. Semiconductor light-e...
