Abstract
Method for fabricating a photodetector includes providing a first substrate containing pixel circuits and common electrode connection members formed therein. A first wiring board material layer is formed on the first substrate and electrically connected to the pixel circuits. A second wiring board material layer is formed on a second substrate and electrically connected to the pixel layers formed therein. The first and second wiring board material layers are bonded. The second substrate, and the second and first wiring board material layers are etched to form through holes with isolation wall members formed therein, the through holes dividing the pixel layer, and the second and first wiring board material layers into pixel units, and second and first wiring boards. Each isolation wall member includes a conductive member and a sidewall between the conductive member and the pixel unit. A transparent electrode layer is formed on the second substrate.
