Abstract:
A method for manufacturing a resin-molded semiconductor device, comprising the steps of:a) preparing a semiconductor chip; b) preparing a leadframe, the leadframe including: an outer rail surrounding an opening, in which the semiconductor chip will be mounted; a die pad provided inside the opening, a central portion of the die pad being elevated above a peripheral portion thereof surrounding the central portion; a plurality of support leads for connecting the die pad to the outer rail, each said support lead including a raised intermediate portion higher in level than the other portion thereof; and a plurality of signal leads, which are connected to the outer rail around the periphery of the opening and extend toward the die pad; c) bonding the semiconductor chip on the central portion of the die pad in the leadframe; d) electrically connecting the semiconductor chip to the signal leads via connection members; and e) molding the semiconductor chip, the die pad, the connection members, the support leads and the signal leads with a resin encapsulant with a seal tape interposed between the backside of the leadframe and a die assembly and with clamping force applied to the leadframe and the seal tape.
