Solid state imaging device having a photodiode and a MOSFET and method of manufacturing the same

摘要

A readout gate electrode (13a) is selectively formed on a silicon substrate. An N-type drain region (14a) is formed at one end of the readout gate electrode (13a), and an N-type signal storage region (15) is formed at the other end thereof. A P+-type surface shield region (21a) is selectively epitaxial-grown on the signal storage region (15), and a silicide block layer (19) is formed on the surface shield region (21a) to cover at least part of the signal storage region (15). A Ti silicide film (33a) is selective epitaxial-grown on the drain region (14a).
