Patent number: 11917314Abstract: An image sensor includes a plurality of pixels. Each pixel includes a photoelectric conversion portion, a reset gate for controlling removal of a charge accumulated in the photoelectric conversion portion, a charge accumulation portion, an accumulation gate for controlling a transfer of the charge from the photoelectric conversion portion to the charge accumulation portion, and a readout gate for controlling readout of the charge from the charge accumulation portion. The reset gate removes the charge generated in the photoelectric conversion portion by excitation light. The accumulation gate transfers the charge generated in the photoelectric conversion portion by fluorescence to the charge accumulation portion. The readout gate performs control for reading out the charge after the charge transfer is performed n times. The number n of the charge transfers is set for each pixel.Type: GrantFiled: September 9, 2020Date of Patent: February 27, 2024Assignee: HAMAMATSU PHOTONICS K.K.Inventors: Ryo Takiguchi, Shinya Ito, Makoto Iwashita, Mitsuaki Kageyama

Publication number: 20230387149Abstract: Provided is an optical sensor including: a charge generation region that generates charges in response to incident light; a charge collection region to which charges generated in the charge generation region are transferred; and at least one transfer gate electrode disposed on a transfer region between the charge generation region and the charge collection region. The charge generation region includes an avalanche multiplication region that causes avalanche multiplication, and a gradient potential energy formation region that forms gradient potential energy that is gradient so that potential energy becomes lower as approaching the transfer region in the charge generation region.Type: ApplicationFiled: October 8, 2021Publication date: November 30, 2023Applicant: HAMAMATSU PHOTONICS K.K.Inventors: Mitsuhito MASE, Ryo TAKIGUCHI, Hiroaki ISHII, Masaru NAKANO, Shin-ichiro TAKAGI
