Abstract:
1. A manufacturing method of a semiconductor device, comprising the steps of: (a) providing a lead frame having a chip mounting portion and a plurality of leads arranged around the chip mounting portion; (b) after the step (a), mounting a semiconductor chip over the chip mounting portion, said semiconductor chip having a front surface, a plurality of electrodes formed over the front surface, and a back surface opposite to the front surface; (c) after the step (b), electrically connecting the leads with the electrodes of the semiconductor chip via a plurality of wires; (d) after the step (c), arranging a lid so as to cover the semiconductor chip and the wires, and bonding the lid to the leads by a sealant; and (e) after the step (d), supplying resin into a space inside the lid with the semiconductor chip arranged therein, thereby sealing the wires and the semiconductor chip with the resin, wherein a shape in a plan view of the lid is comprised of a quadrangle having a first corner, wherein in the step (d), a gap between adjacent ones of the leads is filled with a part of the sealant, and wherein in the step (e), the resin is supplied into the space from the first corner not filled with the sealant.
