shift register

Note: When viewed from the direction of the incident light, the horizontal shift register is

covered with a thick silicon layer (dead layer). However, long-wavelength light

passes through the silicon dead layer and may possibly be detected by the horizontal

shift register. To prevent this, provide light shield on that area as needed.
