Semiconductor device

A semiconductor device comprising:

• a semiconductor substrate having an upper surface and a lower surface located opposite the upper surface;
• a first insulating layer formed on the upper surface;
• a first coil formed on the first insulating layer;
• a second coil formed on the first insulating layer and located adjacent to the first coil in plan view;
• a first conductor pattern formed on the first insulating layer, extending in a second direction perpendicular to a first direction, and formed between the first coil and the second coil in the first direction, the first direction being an arrangement direction of the first coil and the second coil in plan view;
• a second insulating layer formed on the first insulating layer so as to cover the first coil, the second coil, and the first conductor pattern;
• a third coil formed on the second insulating layer and overlapping the first coil in plan view;
• and
• a fourth coil formed on the second insulating layer and overlapping the second coil in plan view,
• wherein the first conductor pattern is electrically connected to the semiconductor substrate.
