1. A light emitting device, comprising:

  • a substrate;

    a nitride semiconductor light emitting cell mounted on the substrate, a top surface of the nitride semiconductor light emitting cell comprising an n-type nitride semiconductor layer or an un-doped nitride semiconductor layer, a bottom surface of the nitride semiconductor light emitting cell comprising a p-type nitride semiconductor layer and a partially exposed n-type nitride semiconductor layer;

    a passivation layer arranged between the substrate and the nitride semiconductor light emitting cell;

    a first metal layer arranged between the substrate and the nitride semiconductor light emitting cell, the first metal layer contacting the bottom surface of the nitiride semiconductor light emitting cell; and

    a bonding pad connected to the first metal layer, the bonding pad arranged on a portion of the substrate and extending outside of a region under the light emitting cell.
