Abstract:
1. A photoelectric conversion element for detecting light and converting the light into photoelectrons, comprising: one metal-oxide-semiconductor (MOS) diode having an electrode formed on a semiconductor substrate with an insulator therebetween; and plural embedded photodiodes that are embedded in the semiconductor substrate, wherein the electrode of the MOS diode has a comb-like shape when viewed from an upper surface thereof, in which plural branch portions are branched from one electrode portion, and the plural embedded photodiodes are nested, respectively, between the branch portions of the electrode when viewed from the upper surface thereof, wherein the potential under the electrode of the MOS diode is controlled, such that the photoelectrons generated by photoelectric conversion at the embedded photodiodes migrate toward the MOS diode.
