Abstract
A readout gate electrode is selectively formed on a silicon substrate. An N-type drain region is formed at one end of the readout gate electrode, and an N-type signal storage region is formed at the other end thereof. A P+-type surface shield region is selectively epitaxial-grown on the signal storage region, and a silicide block layer is formed on the surface shield region to cover at least part of the signal storage region. A Ti silicide film is selective epitaxial-grown on the drain region.
