Abstract
A semiconductor device has a semiconductor substrate, a first insulating layer, a first inductor, a second insulating layer, a second inductor, a pad and an annular wiring. The first insulating layer is formed on the semiconductor substrate. The first inductor is directly formed on the first insulating layer. The second insulating layer is formed on the first insulating layer such that the second insulating layer covers the first inductor. The second inductor is directly formed on the second insulating layer such that the second inductor faces the first inductor. The pad is directly formed on the second insulating layer. The pad is electrically connected with the second inductor. The annular wiring is electrically connected with the pad. The annular wiring is spaced apart from the second inductor. The annular wiring surrounds the second inductor without forming a vertex in plan view.
