A single chip with multi-LED comprises a substrate on which an N-type semiconductor layer, an active layer and a P-type semiconductor layer are successively stacked. At least one N-type electrode is connected to the N-type semiconductor layer, and is exposed to an opening through the active layer and the P-type semiconductor layer. Further, at least one groove divides the P-type semiconductor layer into a plurality of separated regions, and a P-type electrode is disposed on each separated region.
