My Work Summary

******************************
I was teaching graduate and undergraduate students at Sojo university
as a full professor of the information science department since 2009
till 2017. During the period I taught the various courses such as
Engineering Mathematics, Numerical Computational Method,
Semiconductor Device Physics, Digital Circuit and System Design
and Artificial Intelligent Robotics.

I wrote a book entitled as “The world of Digital Circuits” for
the Intelligent Partner System (AIPS) applications in 2016 which
summarizes the most of the scopes of my class teaching materials
focused to the physics of semiconductor and LSI chip designs.

My most important contribution to the world is that my inventions
and my development efforts helped and accelerated the world to
change from the analog to the digital world by replacing the film
and the mechanical shutter technologies by the all solid semiconductor
silicon chips in the field of the intelligent image sensor technology.

Specifically, my 1975 invention of three layer device of pnp dynamic
photo transistor structure, when the two layer photodiode of pn structure
was common at that time, was very unique and is a new dimensional
device for future 3DIC multi-chip integration for artificial intelligent
partner systems with a great deal of freedom for improving image
sensor performances, including super light sensitivity, the most
important characteristics of the image sensor device now used all
over the world.

This is the base of today’s photodiode called PPD or Pinned Photodiode,
which is widely used for various applications including smartphones,
robotics, and self-driving cars to name a few. Sony commercialized
image sensor devices based on his invention, with the trade name
of HAD (Hole Accumulation Diode) sensor, and has become a leading
manufacturer of digital cameras which replaced film cameras completely
in the world.

My 1975 inventions of the back light illumination mode pnp dynamic
photo transistor with in-pixel buffer memory MOS buffer memory
in the global shutter operation mode, is now very essential for
the modern CMOS image sensor applications.

Image sensors, now used for taking fast action pictures, are completely
free from mechanical parts because of my 1975 invention of the electrical
shutter operational four layer device of pnpn dynamic photo thyristor
which has a vertical overflow drain (VOD) structure.

I served many years as an operational committee member, the ISSCC Asian
Program committee chair and the international program chair of IEEE Solid
State Circuit Society sponsored ISSCC conferences in series.

I was also invited as a special guest speaker in CCD1979, ESSCIRC2001,
ESSCIRC2008 and ISSCC2013 for his contributions to the solid state circuits
technology needed to change the image sensor world from the analog
to digital one.

I also served many years as an operational committee member and the conference
chair in the IEEE Electron Device Society sponsored ICMTS conferences in series.

I served as a technical committee member for many years in the international 
standardization committee (IEC) and served as the IEC TC47 technical committee
chair in 1992 in the field of the digital memory chips standardization activities in IEC.

I am a distinguished alumni of California Institute of Technology and IEEE Life fellow.
