Abstract:
1. A solid-state image pickup device comprising: a semiconductor region of a first conductivity-type between a channel portion of the first conductivity-type and a photodiode region of a second conductivity-type, said channel portion and said photodiode region touching said semiconductor region; a gate insulating film between a gate electrode and said channel portion, said semiconductor region touching said photodiode region and said gate insulating film; a first isolation region extending from a front surface of a semiconductor substrate to a back side surface of the semiconductor substrate, said photodiode region and said semiconductor region touching said first isolation region; a second isolation region extending from said front surface to said back side surface, said photodiode region and said semiconductor region touching said second isolation region, wherein said photodiode region is between said first isolation region and said second isolation region, said photodiode region being between said semiconductor region and said back side surface.
