SONY HAD is by definition Pinned Photodiode with the vertical OFD (VOD) function.

Invention of Pinned Photodiode in 1975 by Hagiwara ( in Japanese Text )




The classical MOS image sensor had the N+P junction type photodoide
with the serious image lag problem.

Sony developed the CCD/MOS photo capacitor with no image lag problem.



But the CCD/MOS capacitor has the serious dark current problem.

SONY hole accumulation diode (HAD), which is identical to
the Pinned Photodiode with the vertical overflow drain (VOD)
function, was invented originally by Yoshiaki Hagiwara at Sony.

See the three Japanese patents, 1975-127646, 1975-127647
and 1975-134985 invented by Yoshiaki Hagiwara at Sony in 1975.

In 1978, Hagiwara at Sony developed the P+NPNsub junction type
Pinned Photodiode with the very good blue light sensitivity,
the very low surface dark current and no image lag problem.

The details were disclosed and explained first in the SSDM1978 paper
of the international conference of Solid State Devices and Materials
( http://www.ssdm.jp/ ) and now also in the IEEE 3DIC2019 paper
published at the IEEE international conference of the three Dimensional
Integrated Circuits held at Sendai in Japan. ( https://3dic-conf.org/ )

Hagiwara was on Japanese Television ( Fuji TV ) , March 2013 ,
explaining his vision on the future self-driving automatic car
controlled by with the artificial intelligent partner system (AIPS).
