Abstract
In a back-illuminated solid-state image pickup device, a first group of charge transfer electrodes (vertical shift register) is present in an imaging region, and a second group of charge transfer electrodes (horizontal shift register) is present in a peripheral region around the imaging region. The light incident surface of the semiconductor substratecorresponding to the peripheral region is etched, and an inorganic light shielding substance SH is filled in the etched region. The amount of the inorganic light shielding substance that evaporates and vaporizes under the vacuum environment is extremely small, and the influence on the imaging by the vaporized gas is small.
