摘要： A solid-state imaging device includes: a photoelectric converting section comprising a photo-diode; a charge storage section; a charge transfer section; a first control gate section provided between the photoelectric converting section and the charge storage section to control transfer of a signal charge from the photoelectric converting section to the charge storage section; and a second control gate section provided between the charge storage section and the charge transfer section to control transfer of the signal charge from the charge storage section to the charge transfer section. The charge storage section includes: a first region formed on a side near to the first control gate section; and a second region formed on a side near to the second control gate section and configured to have a channel potential increased more than that of the first region. The second region is configured to hold the signal charge in a pinning condition.
