Claim:
1. A semiconductor device, comprising: a plurality of functional element chips, including a first semiconductor chip and a second semiconductor chip; a first conductor plate configured to join to the first and second semiconductor chips; a second conductor plate configured to join to the second semiconductor chip, and including a step portion that prevents the second chip from falling down; a first wire; and a resin configured to cover the plurality of functional element chips, the first conductor plate and the first wire, wherein the first semiconductor chip includes a gate electrode, a source electrode and a drain electrode, and the gate and source electrodes are configured to face in a same first direction, and the drain electrode faces in a second direction opposite to the first direction, wherein the first conductor plate is joined to the source electrode, wherein the first wire is bonded to the gate electrode through a portion overlapping the first conductor plate in a thickness direction of the first semiconductor chip, and wherein the source electrode of the first semiconductor chip and a drain electrode of the second semiconductor chip are electrically connected via the first conductor plate.
