Abstract

The ground noise is reduced which propagates between circuit elements in a circuit device having a multiple stack structure. A grounding bonding pad provided on the surface of a second circuit element is connected to a bonding wire provided on the surface of a conduction layer via a grounding wire such as gold. A bonding pad provided on the surface of the conductive layer is connected to a lead provided on a ground wire via a grounding wire such as gold. This structure creates a capacitance between the second circuit element and the conduction layer so as to prevent the propagation of noise circuit from element to the ground wiring.
