Abstract:
1. A method manufacturing a semiconductor device, comprising the steps of: bonding, by means of a metal bump, two semiconductor substrates, on respective one-side surfaces of which a conductor layer patterned to a required shape is formed, while facing said respective one-side surfaces; filling, with an insulating resin, a gap between the respective conductor layers bonded by means of the metal bump; polishing each of exposed side surfaces of said semiconductor substrates to thereby thin each of the semiconductor substrates to a prescribed thickness; forming a via hole which reaches the metal bump, in a required place of each of said thinned semiconductor substrates; forming an insulating film on the surface of each of said semiconductor substrates including an inner surface of said formed via hole; opening at least part of a portion in contact with the metal bump, of the insulating film formed within said via hole; filling an inside of said via hole with a conductor and further forming, on said insulating film, an electrode pad patterned to a required shape and electrically connected to the conductor; and stacking a structure obtained by the above-described steps, by a required number, by electrically connecting respective structures with each other through said electrode pad.
