Abstract
Disclosed is a photoelectric transducer having a photodiode that is formed on a second-conductivity-type well and is composed of a first-conductivity-type region to accumulate signal charge when light is supplied and a first second-conductivity-type region formed on the first-conductivity-type region. The first second-conductivity-type region is separated from a second-conductivity-type device separation region and is connected to the second-conductivity-type device separation region at part of the circumference of the first second-conductivity-type region through a second second-conductivity-type region that is formed to be at least partially shallower than the first second-conductivity-type region. Also, disclosed is a solid-state image sensing device equipped with the photoelectric transducer.
