Patent ID: 7724116

Claim:
An inductor, comprising: an insulating layer; a first conductive line disposed in the insulating layer, having a first end and a second end; a second conductive line disposed in the insulating layer, having a first end and a second end, wherein the first end of the second conductive line is electrically connected to the first end of the first conductive line; a third conductive line disposed in the insulating layer, having a first end and a second end, wherein the second end of the third conductive line is electrically connected to the second end of the second conductive line; and a fourth conductive line disposed in the insulating layer, having a first end and a second end, wherein the second end of the fourth conductive line is electrically connected to the second end of the first conductive line; a fifth conductive line disposed in the insulating layer, having a first end and a second end, wherein the first end of the fifth conductive line is electrically connected to the first end of the fourth conductive line; and a sixth conductive line disposed in the insulating layer, having a first end a second end, wherein the first end of the sixth conductive line is electrically connected to the first end of the third conductive line; wherein the first conductive line and the second conductive line are symmetric, and the third conductive line and the fourth conductive line are symmetric; wherein the first conductive line is adjacent to the third conductive line, and the second conductive line is adjacent to the fourth conductive line; wherein the line width of the first, second, third, and fourth conductive lines is not less than 9 μm, and the line space of two adjacent conductive lines is less than the line width of the first, second, third, and fourth conductive lines; wherein the fifth conductive line and the sixth conductive line are symmetric; wherein the third conductive line is adjacent to the fifth conductive line, and the fourth conductive line is adjacent to the sixth conductive line; wherein the line width of the fifth and sixth conductive lines and the line space of two adjacent conductive lines have a first relationship: if the line width exceeds 6 μm, the line space is less than the line width; or if the line width is less than 6 μm, the line space exceeds the line width; or if the line width is equal 6 μm, the line space is equal to the line width.
