Abstract
A semiconductor device is improved in reliability. A power MOSFET for switching, and a sense MOSFET for sensing a current flowing in the power MOSFET, which is smaller in area than the power MOSFET, are formed in one semiconductor chip. The semiconductor chip is mounted over a chip mounting portion, and sealed in a resin. To first and second source pads for outputting the current flowing in the power MOSFET, a metal plate is bonded. A third source pad for sensing the source voltage of the power MOSFET is at a position not overlapping the metal plate. A coupled portion between a source wire forming the third pad and another source wire forming the first and second pads is at a position overlapping the metal plate.
