1. A method of forming a light-emitting device comprising:

  • providing a growth substrate having a front side and a rear side;

    forming a sacrificial layer on the front side of the growth substrate;

    forming a protective structure on the sacrificial layer;

    forming a light-emitting structure on the protective structure, wherein the light-emitting structure emits a first peak wavelength;

    providing a carrier;

    joining the carrier and the light-emitting structure; and

    transforming the sacrificial layer by irradiating a laser beam from the rear side to separate the growth substrate from the light-emitting structure, wherein the laser beam emits a second peak wavelength, and wherein the protective structure reflects the second peak wavelength away from the light-emitting structure;

    wherein the protective structure comprises a first portion and a second portion, wherein the method further comprises removing the first portion, and forming an electrode on the second portion.
