Embodiment 1
[0039] Such as Figure 10 Shown, embodiment one of the present invention is:
[0040] An LED chip structure with electrodes having openings includes an epitaxial structure 1 and an electrode 2 disposed on the epitaxial structure 1 , the electrode 2 includes a bottom and a top opposite to each other, and a side wall connecting the bottom and the top. The top of the electrode 2 is disposed close to the epitaxial structure 1 , and the bottom of the electrode 2 is disposed away from the epitaxial structure 1 .
[0041] The electrode 2 is provided with more than two openings 21 extending from the bottom of the electrode to the top of the electrode, the opening 21 is in the shape of a circular hole, and the distance between the opening 21 and the side wall of the electrode 2 It is provided that more than two openings 21 are evenly distributed at intervals.
[0042] In a preferred embodiment, the apertures of the openings are gradually reduced from the bottom of the electrode to th...
Embodiment 2
[0043] Such as Figure 11 Shown, embodiment two of the present invention is:
[0044]An LED chip structure with electrodes having openings includes an epitaxial structure 1 and an electrode 2 disposed on the epitaxial structure 1 , the electrode 2 includes a bottom and a top opposite to each other, and a side wall connecting the bottom and the top. The top of the electrode 2 is disposed close to the epitaxial structure 1 , and the bottom of the electrode 2 is disposed away from the epitaxial structure 1 .
[0045] The electrode 2 is provided with more than two openings 21 extending from the bottom of the electrode 2 to the top of the electrode 2, and more than two openings 21 are evenly distributed at intervals, and the openings 21 are in the shape of trapezoidal grooves The opening 21 communicates with two opposite side walls of the electrode 2 , wherein the cross-sectional area of the opening 21 near the top of the electrode 2 is smaller than the cross-sectional area of ...
Embodiment 3
[0047] An LED chip structure with an electrode opening includes an epitaxial structure and an electrode arranged on the epitaxial structure, the electrode includes a bottom and a top oppositely arranged, and a side wall connecting the bottom and the top. The top of the electrode is disposed close to the epitaxial structure, and the bottom of the electrode is disposed away from the epitaxial structure.
[0048] The electrode is provided with more than two openings extending from the bottom of the electrode to the top of the electrode, the openings have rough side walls, and the bottom of the openings has a distance from the epitaxial structure.
[0049] This embodiment can also be applied to the first and second embodiments above.
[0050] In an alternative embodiment, the opening extends from the bottom of the electrode to the top of the electrode, communicating with the epitaxial structure.
