Abstract:
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 conductive line and a second conductive line disposed in the first insulating layer and surrounding the center region, wherein each of the first and second conductive lines has a first end and a second end, and wherein the second ends of the first and second conductive lines are coupled to each other; 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 third conductive line and a fourth conductive line arranged from the inside to the outside with respect to the center region, and wherein each of the third and fourth conductive lines has a first end and a second end; and a coupling portion disposed in the first and second insulating layers between the first winding portion and the second winding portion, and comprising: a first pair of connection layers cross-connecting the first ends of the third conductive lines and the first ends of the first and second conductive lines; and a second pair of connection layers cross-connecting the second ends of the third and fourth conductive lines, wherein the first and second conductive lines overlap at least a portion of each of the third conductive lines, and wherein a remaining portion of each of the third conductive lines does not overlap the first and second conductive lines and an area of the overlapping portion is less than that of the remaining portion.
