Abstract
A center of a substrate having peripheral circuit components mounted thereon is hollowed in a size maintaining a distance for establishing a connection with a semiconductor chip through a conductor such that the semiconductor chip is bonded to a heatsink and the peripheral circuit components are arranged near the semiconductor chip so as to surround the semiconductor chip. Upon adhesion of a conductive paste material, for bonding the substrate to the heatsink having the semiconductor chip mounted thereon in a conductive manner, to a bottom face of the substrate, an adhesive tape is stuck to an edge of the substrate so as to prevent outflow of the conductive paste material, respective terminals are connected through conductors, and both the substrate and the heatsink are sealed with a resin.
