Patent ID: 7947528

Claim:
A method of manufacturing a back-illuminated type solid-state image pickup device in which buried wirings connected to a plurality of pixels are formed at a first surface side of a semiconductor substrate wherein at least portions of said plurality of pixels comprising a photo-electric conversion element and a field effect transistor are formed in the semiconductor substrate, a second surface side of said semiconductor substrate opposite the first surface side and being a light receiving side, the method of manufacturing a solid-state image pickup device comprising: forming a plurality of pixels including said photo-electric conversion element and said field-effect transistor at the first surface side of the semiconductor substrate; forming wirings in insulating material to form the buried wirings, connected to said plurality of pixels, at the first surface side of said semiconductor substrate; bonding a supporting substrate to the insulating material formed on said semiconductor substrate; decreasing a thickness of said supporting substrate from a side of the supporting substrate that is opposite a bonding surface; forming penetrating wirings, which pass through said supporting substrate, such that said penetrating wirings are connected to said buried wirings; and decreasing a thickness of a material layer that is formed at the second surface side of the semiconductor substrate.
