Patent number: 9491384Abstract: In a solid-state imaging device 1, an overflow gate (OFG) 5 has a predetermined electric resistance value, while voltage application units 161 to 165 are electrically connected to the OFG 5 at connecting parts 171 to 175. Therefore, when voltage values V1 to V5 applied to the connecting parts 171 to 175 by the voltage application units 161 to 165 are adjusted, the OFG 5 can yield higher and lower voltage values in its earlier and later stage parts, respectively. As a result, the barrier level (potential) becomes lower and higher in the earlier and later stage parts, so that all the electric charges generated in an earlier stage side region of photoelectric conversion units 2 can be caused to flow out to an overflow drain (OFD) 4, whereby only the electric charges generated in a later stage side region of the photoelectric conversion units 2 can be TDI-transferred.Type: GrantFiled: March 25, 2010Date of Patent: November 8, 2016Assignee: HAMAMATSU PHOTONICS K.K.Inventors: Hisanori Suzuki, Yasuhito Yoneta, Kentaro Maeta, Masaharu Muramatsu
