Abstract:
A metal layer is formed by vapor deposition or sputtering on an AlN substrate. Since there are irregularities on the surface of the substrate, irregularities are also formed on the surface of the metal layer. Subsequently, irregularities on the surface of the metal layer are removed and flattened in a mirror state by grinding the surface of the metal layer. Then, a dielectric layer is formed on the metal layer by alternately forming a SiO 2  film and a TiO 2  film through CVD. Next, an electrode layer is formed in a predetermined pattern by vapor deposition and lift-off on the dielectric layer. Since the surface of the metal layer is flattened in a mirror state, reflectance is high on that surface. As a result, the emission efficiency of the light-emitting device can be improved.

Claim (Index 8):
The method for producing a light-emitting device according to  claim 3 , wherein the reflective metal layer is made of a Ti layer formed on the metal layer and at least one of an Al layer and a Ag layer formed on the Ti layer.
