Patent ID: 8440565

Claim:
A method of manufacturing a semiconductor apparatus with an electrode pad and a semiconductor device formed on a surface of a semiconductor substrate, comprising: forming a through-hole that penetrates the semiconductor substrate and thereby exposing the electrode pad at a bottom portion of the through-hole; forming an insulating film on the bottom portion of the through-hole and on an inner wall of the through-hole; forming an adhesion securing layer on the inner wall on which the insulating film has been formed; forming a resist layer on the inner wall on which the adhesion securing layer has been formed; etching the insulating film at the bottom portion of the through-hole with the resist layer as a mask, to thereby expose the electrode pad at the bottom portion of the through-hole; removing the resist layer to expose the adhesion securing layer; and forming a conductive layer on the bottom portion of the through-hole and on the inner wall of the through-hole, the inner wall having the exposed adhesion securing layer by removing the resist layer, and bringing the conductive layer into contact with the electrode pad, wherein the insulating film is formed of a material selected from the group consisting of parylene, polyimide resin, maleimide resin, polyamide resin, polyimide-amide resin, polyester resin, polyether resin, bisphenol resin, modified epoxy resin, modified acrylic resin, silicon resin, fluorocarbon resin, and melamine resin.
