Claim:
1. A semiconductor device comprising: a first semiconductor chip including a first semiconductor substrate, an element formed in an element forming region of the first semiconductor substrate, and a first through-via penetrating across a front surface and a rear surface of the first semiconductor substrate while avoiding the element forming region of the first semiconductor substrate to form a conductive path between the front surface and the rear surface of the first semiconductor substrate; a second semiconductor chip including a second semiconductor substrate, an element formed in an element forming region of the second semiconductor substrate, and a second through-via penetrating across a front surface and a rear surface of the second semiconductor substrate while avoiding the element forming region of the second semiconductor substrate to form a conductive path between the front surface and the rear surface of the second semiconductor substrate; a circuit component mounted on a circuit component connection surface at the same side as the front surface of the first semiconductor substrate of the first semiconductor chip; an electrical connector electrically connecting the first through-via and the second through-via between the rear surface of the first semiconductor substrate and the front surface of the second semiconductor substrate; and an external connection member formed on the rear surface of the second semiconductor substrate.
