Abstract: A semiconductor device can include: a semiconductor chip including a first and second surface, a first electrode on the first surface, an active area on the second surface, a second electrode on the second surface, and a third electrode on the second surface; a first conductive member in the active area of the semiconductor chip and electrically connected to the semiconductor chip; a second conductive member in a second area and isolated from the first conductive member, the second area an area in which, when viewed from above, with respect to a first area of the active area in which the first conductive member is not provided, circles sharing centers of shortest distances between an outer periphery of the first conductive member and an outer periphery of the active area can be drawn largest in the first area; and a lead terminal connected to the first conductive member.
