Abstract:
1. A method for manufacturing a semiconductor device, comprising: preparing a semiconductor substrate with a first notch; preparing a supporting substrate with a second notch; laminating said semiconductor substrate with said supporting substrate so that said first notch can be matched with said second notch; and processing a second main surface of said semiconductor substrate opposite to a first main surface thereof facing to said supporting substrate to reduce a thickness of said semiconductor substrate to a predetermined thickness; forming an active element region on said first main surface of said semiconductor substrate; forming a first wiring layer on said first main surface of said semiconductor substrate so as to be electrically connected with said active element region; forming a through hole at said semiconductor substrate so as to connect said first main surface and said second main surface; and forming a second wiring layer on said second main surface of said semiconductor substrate so as to be electrically connected with said first wiring layer via a conductive layer formed in said through hole.
