Claim Text:
1. A semiconductor light-emitting device, comprising: a first semiconductor layer; a second semiconductor layer between the first semiconductor layer and a conductive substrate; a light-emitting layer between the first semiconductor layer and the second semiconductor layer; a first electrode on a first surface of the first semiconductor layer, the first semiconductor layer being between the first electrode and the light-emitting layer; a first electrode pad on the first surface and electrically connected to the first electrode; a second electrode between the substrate and the second semiconductor layer, a portion of the second electrode not covered by the second semiconductor layer, the light-emitting layer, and the first semiconductor layer; a second electrode pad on the portion of the second electrode and electrically connected to the second electrode, the second electrode pad having an area in a first plane parallel to the conductive substrate that is less than an area of the first electrode pad in a second plane parallel to the first plane; and a third electrode on a second surface of the conductive substrate such that the conductive substrate is between the third electrode and the second electrode, the third electrode being electrically connected to the second electrode pad.
