Semiconductor device having inductor

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, 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 the third conductive lines.
