Abstract
A coil CLis formed on a semiconductor substrate SB via a first insulation film, a second insulation film is formed so as to cover the first insulation film and the coil CL, and a pad PDis formed on the second insulation film. A laminated film LF having an opening OPfrom which the pad PDis partially exposed is formed on the second insulation film, and a coil CLis formed on the laminated insulation film. The coil CLis disposed above the coil CL, and the coil CLand the coil CLare magnetically coupled to each other. The laminated film LF is composed of a silicon oxide film LF, a silicon nitride film LFthereon, and a resin film LFthereon.
