Abstract

Claims (17)

1. An inductor device, comprising:

a first trace, comprising:

a first sub-trace; and

a second sub-trace, disposed directly adjacent to the first sub-trace;

a second trace, comprising:

a third sub-trace, disposed directly adjacent to the second sub-trace; and

a fourth sub-trace, disposed directly adjacent to the third sub-trace;

a first connection member, configured to couple to the first sub-trace;

a second connection member, disposed adjacent to the first connection member, and configured to couple to the second sub-trace;

a third connection member, configured to couple to the third sub-trace; and

a fourth connection member, disposed directly adjacent to the third connection member and the first connection member, and configured to couple to the fourth sub-trace, wherein the first connection member is disposed directly adjacent to the second connection member;

wherein the first sub-trace, the second sub-trace, and the third sub-trace are located on a first layer, and the first connection member and the second connection member are located on a second layer, wherein the first layer and the second layer are different layers.

2. The inductor device of claim 1 , wherein at a first side of a first area, the first sub-trace and the second sub-trace are disposed at an outer side of the inductor device, and the third sub-trace and the fourth sub-trace are disposed at an inner side of the inductor device.

3. The inductor device of claim 2 , wherein at a second side of the first area, the first sub-trace and the second sub-trace are disposed at an inner side of the inductor device, and the third sub-trace and the fourth sub-trace are disposed at an outer side of the inductor device, wherein the first side is corresponding to the second side.

4. The inductor device of claim 3 , wherein at a third side of a second area, the first sub-trace and the second sub-trace are disposed at an outer side of the inductor device, and the third sub-trace and the fourth sub-trace are disposed at an inner side of the inductor device.

5. The inductor device of claim 4 , wherein at a fourth side of the second area, the first sub-trace and the second sub-trace are disposed at an inner side of the inductor device, and the third sub-trace and the fourth sub-trace are disposed at an outer side of the inductor device, wherein the first area is adjacent to the second area, and the third side is corresponding to the fourth side.

6. The inductor device of claim 1 , wherein the fourth sub-trace is located on the first layer, and the third connection member and the fourth connection member are located on the second layer.
