ABSTRACT:
A plurality of semiconductor elements configuring a first element group are stacked in a step-like shape on a wiring board. A plurality of semiconductor elements configuring a second element group are stacked in a step-like shape on the first element group toward a direction opposite to the stepped direction of the first element group. The semiconductor elements are electrically connected to connection pads of the wiring board through metallic wires. Among the plurality of semiconductor elements configuring the second element group, the lowermost semiconductor element has a thickness larger than those of the other semiconductor elements.
