A light emitting chip includes a substrate, a reflective layer, a light emitting structure and a first electrode having a base formed between the reflective layer and the substrate. The light emitting structure includes a first semiconductor layer, an active layer and a second semiconductor layer. The first electrode further includes a connecting section extending upwardly from the base. An electrically insulating ion region is defined in the light emitting structure and extends from an upper surface of the base to the first semiconductor layer. A receiving groove is defined in the ion region and extends upwardly from the upper surface of the base to the first semiconductor layer. The connecting section is positioned in the receiving groove and electrically connects with the first semiconductor layer.
