Abstract:
1. A semiconductor light emitting element having a cross-sectional structure comprising: a support substrate; a semiconductor lamination located over the support substrate, containing at least a p-type semiconductor layer, an active layer having a light emitting characteristic, and an n-type semiconductor layer; and a joint layer located between the semiconductor lamination and the support substrate, containing a first jointing layer located on a semiconductor lamination side and a second jointing layer located on a support substrate side, and fixing a positional relationship between the semiconductor lamination and the support substrate by joining the first and second jointing layers, wherein in a plan view: the semiconductor lamination has corner portions and side portions along a periphery thereof; the first jointing layer is encompassed by the second jointing layer; and an annular region defined between an outline of the semiconductor lamination and an outline of the first jointing layer has first portions corresponding to the corner portions of the semiconductor lamination and second portions corresponding to the side portions of the semiconductor lamination, widths of the first portions being narrower than widths of the second portions.
