摘要:
A wafer supporting plate is formed of a glass or a resin which can permeate ultraviolet rays and has a nearly disk shape. An outer diameter of the wafer supporting plate is larger than that of the semiconductor wafer which is supported. In the wafer supporting plate, a plurality of openings are formed to correspond to plural through holes of the semiconductor wafer. The opening has an open area larger than an open area of the through hole, that is, has a larger diameter.

A semiconductor device comprises a semiconductor substrate having an through hole, a first insulation resin layer formed on an inner surface of the through hole, a second insulation resin layer formed on at least one of front and rear surfaces of the semiconductor substrate, and a first conductor layer formed in the through hole to connect at least both front and rear surfaces of the semiconductor substrate and insulated from the inner surface of the through hole with the first insulation resin layer. A second conductor layer (wiring pattern) which is electrically connected to the first conductor layer in the through hole is further provided on the second insulation resin layer. The conductor layer formed in the through hole and constituting a connecting plug has a high insulation reliability. Therefore, a semiconductor device suitable for a multi-chip package and the like can be obtained. Further, since the forming ability of the conductor layer connecting the front and rear surfaces and the insulation layer is high, the manufacturing cost can be reduced.

When a resin 59 to form a molded body 20 is poured and a lead frame 30 is attached to a front end face 21 of the molded body 20 by insert molding, protective leads 32 provided on both outsides of a lead pattern 31 of the lead frame 30 moderate the flow of the resin 59 and the force acting on the lead pattern 31 is decreased, so that misregistration of the lead pattern 31 can be prevented. Accordingly, the inserted and molded lead frame 30 can be wired on the front end face 21 of the molded body 20 for easily accomplishing three-dimensional electric wiring.
