Patent ID: 6903374

Claim:
A structure of a p-electrode formed at the light-emerging side of a light-emitting diode (LED), the LED comprising: (a) an n-type semiconductor substrate; (b) an n-type cladding layer formed over the n-type semiconductor substrate; (c) an active layer formed on the n-type cladding layer; (d) a p-type cladding layer formed on the active layer; (e) a p-type contact layer formed over the p-type cladding layer, with a p-type semiconductor layer between the p-type cladding layer and the p-type contact layer; and (f) an n-electrode formed on the back face of the n-type semiconductor substrate; the structure comprising: (g) a mesh-shaped semi-transparent thin-film metal electrode for diffusing electric current formed on the p-type contact layer, the metal electrode having: (g1) a covering portion having a transmittance of at least 10%; and (g2) an opening portion being formed of a multitude of windows and having an opening ratio of at least 20%; and (h) a bonding electrode for wire bonding, the bonding electrode being: (h1) formed at the periphery of the p-type contact layer; and (h2) bonded directly to the mesh-shaped semi-transparent thin-film metal electrode.
