Patent ID: 6894394

Claim:
A method for manufacturing a semiconductor device, comprising: (a) forming electrical interconnections over a surface of a semiconductor substrate having integrated circuits; (b) providing a plurality of bonding pads disposed on the surface of the semiconductor substrate; (c) electrically connecting the electrical connections to respective bonding pads of the plurality of bonding pads; (d) electrically connecting the plurality of bonding pads to each of the integrated circuits; (e) forming resin layers so as to cover the electrical interconnections; (f) forming concave portions by a first process, each of the concave portions being disposed in a corresponding portion of the resin layers that cover the electrical interconnections; (g) curing the resin layers having the concave portion; (h) forming through-holes by removing bottoms of the concave portions by a second process that differs from the first process; and (i) forming external connection terminals, each being disposed on a corresponding area of the electrical interconnections exposed through the through-holes.
