Patent ID: 7220617

Claim:
A method for manufacturing a semiconductor device having, (a) a step of preparing a conductive cap, (b) a step for housing a semiconductor chip within a region enclosed by an upper part and a side part of the conductive cap, and (c) a step sealing the semiconductor chip by a resin sealing body, wherein the conductive chip integrally has the upper part, the side part, and a leg, and the semiconductor chip has a first surface and a second surface, which are positioned at sides opposite to each other, an upper electrode formed on the first surface, and first and second lower electrodes formed on the second surface; the step (b) has (b1) a step of mounting the semiconductor chip within the region enclosed by the upper part and the side part of the conductive cap via a conductive, connection material for cap connection between the upper electrode of the semiconductor chip and the upper part of the conductive cap, (b2) a step of mounting first and second, external connection terminals on the first and the second, lower electrodes of the semiconductor chip via first and second, connection materials respectively, and (b3) after the steps (b1) and (b2), the connection material for cap connection, the first connection material and the second connection material are heated and melted, thereby the upper electrode of the semiconductor chip is bonded to the upper part of the conductive cap via the connection material for cap connection, the first lower-electrode of the semiconductor chip is bonded to the first external connection terminal via the first connection material, and the second lower electrode of the semiconductor chip is bonded to the second external connection terminal via the second connection material, and the step (c) has (c1) a step of filling the resin sealing body into the region enclosed by the upper part and the side part of the conductive cap such that the semiconductor chip is covered and the first and the second, external connection terminals are exposed, and (c2) a step of heating and curing the resin sealing body.
