Claim:
1. A semiconductor device, comprising: a first insulating layer and a second insulating layer sequentially disposed on a substrate having a center region; a first winding portion and a second winding portion disposed in the second insulating layer and surrounding the center region, wherein each of the first and second winding portions comprises a first conductive line, a second conductive line and a third conductive line arranged from the inside to the outside and each conductive line has a substantially uniform width, and wherein each of the first, second and third conductive lines has a first end and a second end, and wherein the first ends of the first conductive lines are coupled in the second insulating layer; and a coupling portion disposed in the first and second insulating layers between the first and second winding portions, and comprising: a first pair of connection layers cross-connecting the second ends of the first and second conductive lines; and a second pair of connection layers cross-connecting the first ends of the second and third conductive lines, wherein a plurality of spacings between the first conductive lines and the second conductive lines adjacent thereto are different, as measured along a plurality of lines orthogonally intersecting the first conductive lines, the second conductive lines, and the third conductive lines, and wherein at least one of the plurality of spacings between the first conductive lines and the second conductive lines adjacent thereto is greater than a spacing between the second conductive lines and the third conductive lines adjacent thereto, as measured along a line of the plurality of lines orthogonally intersecting the first conductive lines, the second conductive lines, and the third conductive lines, and wherein the plurality of spacings belongs to a same one inductor, wherein the first ends of the first conductive lines are directly connected, wherein the first conductive line of the first winding portion continuously extends from the second end of the first conductive line of the first winding portion towards the first end of the first conductive line of the first winding portion, and wherein the first conductive line of the second winding portion continuously extends from the second end of the first conductive line of the second winding portion towards the first end of the first conductive line of the second winding portion.
