A semiconductor device including a first insulating layer and a second insulating layer sequentially disposed on a substrate having a center region. The semiconductor device includes a first winding portion and a second winding portion disposed in the second insulating layer and surrounding the center region A second conductive line and a third conductive line are arranged from the inside to the outside. In addition, each of the first, second and third conductive lines has a first end and a second end. The semiconductor device also includes a coupling portion disposed in the first and second insulating layers between the first and second winding portions, and having 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.
