Abstract:
1. A semiconductor device comprising: a semiconductor substrate; at least one through hole formed through said semiconductor substrate between front and back surfaces of said semiconductor substrate; an electrical connection portion formed by a semiconductor process on at least one surface of the front and back surfaces of said semiconductor substrate in a vicinity of an end opening of said through hole; an insulating layer formed of an organic material on at least an inside surface of said through hole; and an electroconductive layer formed on at least an inside surface of said insulating layer, wherein the organic material comprises a binder resin which is selected from a group consisting of a denatured epoxy resin, a polyamide resin, a polyimide resin, a maleimide resin, a polyimide-amide resin, a polyester resin, a polyether resin, a bisphenol resin, a denatured acrylic resin, a silicone resin, a fluorocarbon resin, and a melamine resin, or a resin mixture obtained by suitably combining these resins, and is cured at a temperature less than or equal to 4000° C. with one of polymerization reaction-generated bonding, condensation reaction-generated bonding, addition reaction-generated bonding, urethane bonding, urea bonding, ester bonding, ether bonding, carbonate bonding, thiourethane bonding, thioester bonding, thioether bonding, amide bonding, unsaturated bonding, and siloxane bonding, and wherein said electrical connection portion is electrically connected to said electroconductive layer to be electrically connected to a side of the other surface of said semiconductor substrate.
