Abstract

This disclosure discloses a light-emitting device. The light-emitting device is configured to electrically connect to an external circuit and comprises: a first light-emitting structure; a second light-emitting structure; a first conductive structure comprising a first connecting pad having a side surface and a top surface connected to the first light-emitting structure, and a first connecting portion extending from the side surface and connected to the external circuit; and a second conductive structure electrically connecting the first light-emitting structure with the second light-emitting structure.

Claims (21)

1. A light-emitting device, comprising:

a first light-emitting structure having an active layer;

a second light-emitting structure;

a first conductive structure overlapping the active layer in a view and comprising:

a first connecting pad having a side surface and a top surface connected to the first light-emitting structure; and

a first connecting portion extending away from the side surface without being directly connected to the second light-emitting structure; and

a second conductive structure electrically connecting the first light-emitting structure and the second light-emitting structure without overlapping the active layer,

wherein the active layer is overlapped with the first conductive structure but not overlapped with the second conductive layer.

2. The light-emitting device of claim 1 , further comprising a carrier attached to the first light-emitting structure and the second light-emitting structure.

3. The light-emitting device of claim 2 , wherein the first connecting portion extends out an edge of the carrier.

4. The light-emitting device of claim 1 , further comprising a carrier with a topmost surface which on the first connecting portion is formed.

5. The light-emitting device of claim 1 , further comprising a transparent material enclosing the first light-emitting structure, the second light-emitting structure, and a portion of the first connecting portion.

6. The light-emitting device of claim 1 , further comprising a transparent material enclosing a sidewall of the first connecting portion.

7. The light-emitting device of claim 1 , wherein the second connecting structure comprises a second connecting pad, a third connecting pad, and a second conductive portion arranged between and electrically connects the second connecting pad with the third connecting pad.

8. The light-emitting device of claim 7 , wherein the second connecting pad is physically bonded to the first light-emitting structure and the third connecting pad is physically bonded to the second light-emitting structure.

9. The light-emitting device of claim 1 , wherein the light-emitting device is free of a carrier.

10. The light-emitting device of claim 1 , wherein the first connecting portion has two opposite sides exposed to ambient environment.

11. The light-emitting device of claim 1 , wherein the first connecting portion has a width less than that of the first connecting pad.

12. The light-emitting device of claim 1 , wherein the first connecting pad has a height equal to that of the first connecting portion.

13. The light-emitting device of claim 1 , wherein the first connecting portion comprises Cu, Au, Pt, Ti, or Ni.

14. The light-emitting device of claim 1 , wherein the first connecting pad and the first connecting portion are substantially positioned at a height level.
