Abstract:
1. A semiconductor light-emitting device, comprising: a light-emitting epitaxial structure having a first surface and a second surface opposite to said first surface, wherein said light-emitting epitaxial structure has a first zone and a second zone enclosing said first zone; a first electrode structure disposed over said first zone and in electrically contact with said first surface; a second electrode structure disposed over said second zone and in electrically contact with said first surface; a light reflective metal layer disposed adjacent to said second surface; a resistivity-enhancing structure disposed adjacent to a surface of said light reflective metal layer and corresponding to a position of said first electrode structure, wherein said surface of said light reflective metal layer is away from said second surface; a protection ring having a first portion and a second portion, wherein said first portion surrounds and contacts with a sidewall of said light reflective metal layer, wherein said second portion is corresponding to a position of said second electrode structure and in contact with said surface of said light reflective metal layer; a buffer layer disposed adjacent to said light reflective metal layer and said resistivity-enhancing structure; a binding layer disposed adjacent to said buffer layer and away from said light reflective metal layer; a substrate disposed adjacent to said binding layer and away from said buffer layer; and a third electrode structure in electrically contact with said substrate.
