Patent ID: 7075115

Claim:
A light-emitting diode comprising a laminated-layer construction of semiconductor having an n-type contact layer of nitride semiconductor with an n-side electrode, a p-type contact layer of nitride semiconductor with a p-side electrode, and an active layer of nitride semiconductor, wherein the n-side electrode and the p-side electrode are provided on the same electrode-forming-plane side, wherein the n-type contact layer has a first area where the laminated-layer construction of semiconductor with the p-side electrode is provided, and a second area which is different from the first area as viewed from the electrode-forming-plane side, wherein a plurality of bumps and dips is formed in the second area, wherein a top level of the plurality of bumps and dips is positioned on the p-type contact layer side of the active layer in a cross-sectional view of the light-emitting diode, wherein the bottom level of the plurality of bumps and dips is positioned on the n-type contact layer side of the active layer in the cross-sectional view of the light-emitting diode, and wherein each of the bumps is formed in the shape of a trapezoid, which becomes gradually thinner in a direction toward the p-type contact layer side as viewed in a cross-sectional view of the bumps and dips.
