Claim Text:
1. A method of producing a solid-state image pickup device comprising: a step of forming an interlayer insulating film on a face side surface of a semiconductor substrate, the face side surface of the semiconductor substrate is opposite to a different surface of the semiconductor substrate; a step of forming a semiconductor substrate support member on the interlayer insulating film, the interlayer insulating film is between the semiconductor substrate and the substrate support member; a step of forming an opening through the substrate support member, the opening extends from a surface of the substrate support member to an electrically conductive pad in the interlayer insulating film; and a step of chemical mechanically polishing the different surface of the semiconductor substrate to expose a back side surface of the semiconductor substrate, the step of forming the opening occurs prior to the step of chemical mechanically polishing the different surface of the semiconductor substrate.
