Abstract
A zener diode is formed in a spacer, which adhered on the semiconductor substrate so as to surround an image sensor, by semiconductor process. A first contact terminal is connected to a CCD output terminal of the image sensor, and a second contact terminal is connected to a ZD ground terminal on the semiconductor substrate. When the ZD ground terminal is connected to ground, the zener diode is actuated. Capacitance components of the zener diode smoothes a waveform of the CCD output so as to prevent an unnecessary radiation noise from generating.
