Abstract:
A method for manufacturing a vertical CMOS image sensor related to a semiconductor device is disclosed. A high-temperature double annealing process and/or an additional passivation nitride film are selectively applied in order to improve dark leakage characteristics and also to prevent or reduce an incidence of circular defects, thereby enhancing the quality and reliability of the vertical CMOS image sensor.
