Abstract:
1. A method of manufacturing a solid-state image pickup device, said solid-state image pickup device including, in a semiconductor substrate, a photoelectric conversion section configured to convert incident light into a signal charge, a transfer transistor configured to read the signal charge from said photoelectric conversion section and transfer the signal charge, and an amplifying transistor configured to amplify the signal charge read by said transfer transistor, said method comprising the steps of: forming, after forming said amplifying transistor in said semiconductor substrate, an insulating film on said semiconductor substrate, and then forming an opening part in said insulating film on said amplifying transistor; forming a compressive stress film covering said amplifying transistor and having a compressive stress on said insulating film; and leaving said compressive stress film in said opening part on said amplifying transistor and removing said compressive stress film on regions other than said opening part.
