Abstract:
1. A semiconductor device comprising: a wiring board having a core material which has a top surface and a bottom surface opposite the top surface, a first insulating film being formed over the top surface of the core material, and a plurality of bonding leads being disposed around the first insulating film; a semiconductor chip having an obverse surface over which a plurality of electrode pads are formed and a reverse surface opposite the obverse surface and being mounted over the first insulating film via a die bonding material; and a plurality of metal wires electrically connecting to the plurality of bonding leads of the wiring board and the plurality of electrode pads, respectively, wherein each of the plurality of bonding leads has a first part and a second part outside the first part, wherein, in plan view, a plane area of the first insulating film is smaller than a plane area of the semiconductor chip, and wherein, in cross-section view, an end portion of the die bonding material is located in a space portion defined by a side surface of the first insulating film, the reverse surface of the semiconductor chip, the top surface of the core material, and a side surface of the first part of each of the plurality of bonding leads.
