Abstract
There is provided a semiconductor device in which a wiring inductance of a DC/DC converter formed on a multi-layered wiring substrate can be reduced and the characteristics can be improved. In the semiconductor device, in an input-side capacitor, one capacitor electrode is electrically connected to a power-supply pattern between a control power MOSFET and a synchronous power MOSFET, and the other capacitor electrode is electrically connected to a ground pattern therebetween. The multi-layered wiring substrate includes: a via conductor arranged at a position of the one capacitor electrode for electrically connecting among a plurality of power-supply patterns in a thickness direction; and a via conductor arranged at a position of the other capacitor electrode for electrically connecting among a plurality of ground patterns in a thickness direction.
