1. A method for manufacturing a light emitting device, comprising:

  • step (a);

    providing a semiconductor wafer comprising a substrate and at least one epitaxial structure, wherein the epitaxial structure comprises;

    a first type semiconductor layer;

    a second type semiconductor layer, disposed on the substrate, wherein the first type semiconductor layer is located on the second type semiconductor layer; and

    a light emitting layer, disposed between the first type semiconductor layer and the second type semiconductor layer;

    step (b);

    forming an electrode connection layer on the epitaxial structure, wherein the electrode connection layer comprises a plurality of connection pads, a plurality of first electrodes and a plurality of second electrodes, the first electrodes and the second electrodes are separated from each other and are connected to the corresponding connection pads, and are located at a same side of the epitaxial structure, wherein the first electrodes and the second electrodes are electrically connected to the first type semiconductor layer and the second type semiconductor layer to define a plurality of light emitting units;

    step (c);

    providing a package substrate having a similar size as that of the semiconductor wafer, wherein the package substrate has a plurality of conductive through holes penetrating through the package substrate;

    step (d);

    bonding the semiconductor wafer and the package substrate by aligning the connection pads of the electrode connection layer with the conductive through holes, so that the conductive through holes are electrically connected to the first type semiconductor layer or the second type semiconductor layer; and

    step (e);

    removing the substrate to expose a surface of the epitaxial structure, so as to form the light emitting device.
