Original Patent Claims translated in English Language,



This is a very old forgotten patent of mine filed in November 10, 1975.

Hagiwara filed two more Japanese patents before this JAP1975-134985.

They are JAP1975-127646 and JAP1975-127647. These two patents
were intended to be applied in the three dimensional image sensor system
with the back light illumination scheme and the MOS buffer memory
for the global shutter function which is very much needed in the modern
three dimensional high performance CMOS image sensor structures.



Imediately after Hagiwara joined SONY on February 20, 1975, with a
very fresh idea, Hagiwara filed these three basic patents on Pinned
Photodiode and SONY HAD concept.

Hagiwara forgot completely the details of these patents and did not
disclose the details to the international community. And no one
including Hagiwara himself did not pay atention to these patents.

****************************************
Sorry, it was all Hagiwara's problem making so
much confusions to the image sensor world.
****************************************

Recently Hagiwara published in the 3DIC2019 conference a paper titled

"Multichip CMOS Image Sensor Structure for Flash Image Acquisition"

"the World of Artificial Intelligent Digital Circuits",
***********************************************************

Hagiwara wrote a book on "the World of Artificial Intelligent Digital Circuits",
which is important and needed to built the inteligent image sensor systems.

The book reviews first the elementary mathematics needed to understand
the basics of Semiconductor Device Physics and Digital Cirucuit Design
needed to construct an Artificial Intelligent Partner System (AIPS) using
the intellignet machine vision chips and powerful micro coltrol chips.
