Abstract:
1. A method of manufacturing a semiconductor device comprising: preparing a semiconductor substrate having an integrated circuit unit and an electrode pad electrically coupled to the integrated circuit unit above a first surface; reducing a thickness of the semiconductor substrate by grinding a second surface opposite to the first surface; forming a hole that extends from the second surface to the electrode pad, such that the hole exposes the surface of the electrode pad at a bottom of the hole; forming an insulating film to cover an inner surface of the hole; forming an opening by selectively removing a part of the insulating film extending parallel to the surface of the electrode pad and covering the surface of the electrode pad at the bottom of the hole such that a part of the surface of the electrode pad exposed by the hole is exposed by the opening while the remaining part of the surface of the electrode pad is covered by the remaining art of the insulation film extending parallel to the surface of the electrode pad; and filling a metal material in the hole to couple to the electrode pad.
