Abstract
Photodetectors and fabrication methods thereof and imaging sensors are provided. An exemplary photodetector includes a first substrate formed with pixel circuits and common electrode connection members and first wiring boards electrically connected to the corresponding pixel circuits; and a second substrate formed with pixel units and isolation wall members isolating pixel units. Each isolation wall member includes a conductive member and a sidewall; second wiring boards are formed on a front surface of the second substrate; the second wiring boards are electrically connected to first terminals of the pixel units; a transparent electrode layer is formed on a back surface of the second substrate; and a second terminal of each pixel unit is electrically connected to the transparent electrode layer. The second wiring boards are bonded and electrically connected to the first wiring boards and the transparent electrode layer is electrically connected to the common electrode connection members.
