ABSTRACT:
A semiconductor device of the present invention in which a plurality of lead terminals are provided for only one side, comprising a plurality of leads connected to the lead terminals, a semiconductor chip provided on an island and having a plurality of pads electrically connected to the leads on one side, a first extension lead which is connected to one lead terminal among the leads and at least a part of which is provided along a side of the semiconductor chip perpendicular to the side of it having the pads, a second extension lead at least a part of which is provided for a side of the semiconductor chip opposite to the side of it having the pads, and a suspension pin provided between one end of the first extension lead and one end of the second extension lead and connected to the island. The semiconductor chip includes a power-supply-voltage provided for a side of the semiconductor chip opposite to the side of it having the pad and pad electrically connected with the other end of the second extension lead, a first auxiliary pad provided for a side of the semiconductor chip other than the side of it having the pads and electrically connected to one end of the first extension lead and a second auxiliary pad electrically connected to one end of the second extension lead, and wiring connecting the first auxiliary pad with the second auxiliary pad.
