To transfer all charges retained in a charge retention region. The photoelectric converter generates a charge corresponding to the exposure amount during a predetermined exposure period. The generated-charge retention portion and the output charge retention portion retain the charge. The generated-charge transfer portion transfers the charge from the photoelectric converter to the generated-charge retention portion to perform the generated-charge transfer after the elapse of the exposure period. The retained-charge transfer portion transfers the charge retained in the generated-charge retention portion to the output charge retention portion to perform the retained-charge transfer. The generated-charge retention gate portion applies a control voltage that is a voltage for controlling potential of the generated-charge retention portion to the generated-charge retention portion during a period of the generated-charge transfer and the retained-charge transfer, applies a bias voltage that is a voltage having a polarity different from the control voltage to the generated-charge retention portion during a period different from the period of the generated-charge transfer and the retained-charge transfer, and applies the bias voltage to the generated-charge retention portion after applying an approximately intermediate voltage between the control voltage and the bias voltage to the generated-charge retention portion at the end of the period of the retained-charge transfer.

Forming a back-illuminated type CMOS image sensor, includes process for formation of a registration mark on the wiring side of a silicon substrate during formation of an active region or a gate electrode. A silicide film using an active region may also be used for the registration mark. Thereafter, the registration mark is read from the back-side by use of red light or near infrared rays, and registration of the stepper is accomplished. It is also possible to form a registration mark in a silicon oxide film on the back-side (illuminated side) in registry with the registration mark on the wiring side, and to achieve the desired registration by use of the registration mark thus formed.

A solid-state image pickup device includes a plurality of pixels, a pixel connection section, and a pixel reset section. The plurality of pixels each include a photoelectric conversion section that generates a charge according to irradiated light, a charge holding section that holds the generated charge, and a signal generation section that generates as an image signal a signal according to the held charge. The pixel connection section conducts between charge holding sections of the plurality of pixels and thereby allows each of the charge holding sections of the plurality of pixels to hold the charge that has been generated by the photoelectric conversion section of one pixel of the plurality of pixels. The pixel reset section discharges and resets the charge of the respective charge holding sections of the plurality of pixels when the pixel connection section conducts between the respective charge holding sections of the plurality of pixels.
