SEMICONDUCTOR LIGHT RECEIVING DEVICE AND FABRICATING METHOD THEREOF TO IMPROVE LIGHT COLLECTION EFFICIENCY AND PLAN TO INCREASE SENSITIVITY OF EACH LIGHT RECEIVING REGION

摘要

PURPOSE: A semiconductor light receiving device is provided to improve light collection efficiency and plan to increase sensitivity of each light receiving region by rounding a corner of a transfer electrode adjacent to a light receiving region. CONSTITUTION: A light receiving region is formed on a semiconductor substrate(1). An electrode is formed in the periphery of the light receiving region on the semiconductor substrate to transfer the charges generated by the photoelectric transformation in the light receiving region to the outside of the light receiving region. A part or all of the periphery of the electrode is processed to move back toward the center of the electrode so that the electrode can be separated from the semiconductor substrate.
