Patent ID: 7473977

Claim:
A method of driving a solid-state imaging device which transfers, by means of a charge-coupled device, an electric signal obtained by photoelectric conversion in a sensor portion, and which includes a light-shielding film that has an opening above the sensor portion but covers a non-photoelectric-conversion area on the side of the sensor portion, the method including the step of: applying a DC voltage to said light-shielding film when reading out said electric signal from said solid-state imaging device, wherein, said light-shielding film is formed of a plurality of layers, in which a first light-shielding film layer in said plurality of layers is provided with an opening above said sensor portion while covering the non-photoelectric-conversion area on the side of said sensor portion, and which is grounded, and a second light-shielding film layer is formed on a light-shielding film layer positioned under the second light-shielding film layer with an insulating film in between them, so as to project from one side of the opening of said light-shielding film layer toward said sensor portion, to which a DC voltage is applied.
