Claim 0:
1. A semiconductor light-emitting device, comprising:
a growth substrate;
a light-emitting structure on the growth substrate, the light-emitting structure including a first semiconductor layer, an active layer, and a second semiconductor layer sequentially stacked;
a first insulating layer on the light-emitting structure and the growth substrate, the first insulating layer including a plurality of first openings and a plurality of second openings;
a second insulating layer on the first insulating layer, the second insulating layer including a third opening;
a first sub-electrode layer between the second semiconductor layer and the first insulating layer;
a second sub-electrode layer between the first insulating layer and the second insulating layer, the second sub-electrode layer being connected to the first sub-electrode layer through the plurality of second openings;
a first electrode and a second electrode on the second insulating layer, the first electrode being connected to the first semiconductor layer through the plurality of first openings, and the second electrode being connected to the second sub-electrode layer through the third opening;
a first metal interconnection on the first electrode; and a second metal interconnection on the second electrode,
wherein in a first one of the plurality of second openings, the second sub-electrode layer, the second insulating layer, and the first electrode extend along a side surface of the first one of the plurality of second openings, and in a second one of the plurality of second openings, the second sub-electrode layer, the second insulating layer, and the second electrode extend along a side surface of the second one of the plurality of second openings, and
wherein a total area of the plurality of first openings measured at a top surface of the first semiconductor layer is smaller than a total area of the plurality of second openings measured at a top surface of the first sub-electrode layer.
