2. Description of the Related Art
The accompanying drawings are included to provide easy understanding of the application, and are incorporated herein and constitute a part of this specification. The drawings illustrate embodiments of the application and, together with the description, serve to illustrate the principles of the application.
FIGS. 1A-1B and 1D-1G illustrate a process flow of a method of fabricating an optoelectronic device of the first embodiment in the present disclosure;
FIGS. 1C and 1H illustrate scanning electron microscope (SEM) pictures of the first embodiment in the present disclosure;
Reference is made in detail to the preferred embodiments of the present application, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
The present disclosure describes an optoelectronic device and a method of fabricating the optoelectronic device. In order to have a thorough understanding of the present disclosure, please refer to the following description and the illustrations.
FIGS. 1A to 1F illustrate a process flow of the method of fabricating the optoelectronic device of first embodiment of the present disclosure. FIG. 1A shows a substrate 101 having a normal direction N1 and a first major surface 1011. A first transition layer 1021 is formed on the first surface 1011 of the substrate 101 and has a normal direction N2 wherein the thickness of the first transition layer 1021 can be 0.3-3 μm, 0.4-3 μm, 0.5-3 μm, 0.7-3 μm, 1-3 μm, or 2-3 μm.
