PROBLEM To provide a high quality solid state image pickup device.
SOLUTION Impurities are implanted into a semiconductor substrate to form
vertical transfer channels for transferring electric charges in a first
direction and to form a drain near each of the vertical transfer channels
via a gate which forms a barrier. A first silicon oxide film, a silicon
nitride film and a second silicon oxide film are deposited in this order
from the bottom, on the surfaces of the vertical transfer channels, gates
and drains. A first layer vertical transfer electrode is formed on the
second silicon oxide film above the vertical transfer channel, and an
insulating film if formed on the surface of the first layer vertical
transfer electrode. The second silicon oxide film and silicon nitride
film are etched in such a manner that the silicon nitride film covers the
vertical transfer channel and extends above the gate excepting a portion
near the drain. A gate control electrode is formed on the insulating film
and first silicon oxide film. A plurality of charge accumulation regions
are formed in a matrix shape in an area defined on an upstream side of
the first direction further than the drains, in such a manner that each
column of the charge accumulation regions is formed near each of the
vertical transfer channels.
