Abstract:
A semiconductor device comprising:a semiconductor chip which has a semiconductor die and a plurality of electrodes; a plurality of leads which are arranged around the semiconductor chip, a tab which has a size smaller than a size of a main surface of the semiconductor chip and is bonded to a back surface of the semiconductor chip; a plurality of suspending leads which are connected to the tab and to which bent portions are formed so as to form stepped portions with respect to the tab; common lead portions which are connected to the suspending leads and have at least portions thereof arranged outside the semiconductor chip; a plurality of first wires which electrically connect a plurality of electrodes of the semiconductor chip with a plurality of leads respectively; second wires which electrically connect electrodes of the semiconductor chip with the common lead portions; and a sealing body which seals the semiconductor chip, the first and the second wires, the tab and the common lead portions using resin, wherein a plurality of leads and a plurality of suspending leads have respective portions thereof exposed to a mounting surface of the sealing body, and wherein a distance between a suspending lead exposing portion and a lead exposing portion disposed close to the suspending lead exposing portion on the mounting surface is set to a value equal to or more than a distance between the neighboring lead exposing portions on the mounting surface.
