Abstract: PURPOSE:To get the specific arc function including defect repair function by applying a high energy beam to the PN junction part of a photodiode, which constitutes a picture element cell, so as to break it. CONSTITUTION:For the picture element cell having a defect, a high energy beam such as a laser beam is applied to the photodiode to break the junction part (N' and P). Hence, the photodiode PD, having a defect is fixed at a potential equal to the potential in a P well region, as shown by the potential distribution diagram in the figure (B). Accordingly, from the output terminal of a CCD type solid-state image pickup element, the signal that-is outputted from the photodiode whose junction is broken and that is at the level greatly different from an ordinary picture element signal is output. Hereby, the defect can be repaired making use of defect picture element information in the output signal or specific address information, or it can be used as the mark representing a specific display information.
