Patent attributes
Two vertical-type power MISFETs are formed over a semiconductor chip, a common drain electrode formed over a back surface of the semiconductor chip is electrically connected with a drain terminal via a conductive bonding material, source electrodes and gate electrodes formed over a surface of the semiconductor chip are respectively electrically connected with source terminals and gate terminals via bump electrodes, and these components are sealed by a resin sealing portion. The exposed portions of the gate terminals are arranged inside the resin sealing portion, and the exposed portions of the source terminals are arranged outside the resin sealing portion. The source terminals extend over the surface of the semiconductor chip and are connected with the source electrodes which are uniformly arranged over regions of the surface of the semiconductor chip except for gate electrode forming regions and the vicinities of these regions via the bump electrodes.
