Sony EX-President Kazuo Iwama attended the First IEEE ISSCC1954conference,
was the leader and the father of Sony's Devlopment Eforts for Bipolar Transistor
and Sony Portable Transistor Radios, and is now considered to be the Father of
Sony's Development Efforts of CCD and CMOS Image Sensor Products. Hagiwara
published his PhD thesis paper on the charge transfer analysis of the Buried
Channel CCD image sensors in the ISSCC1974 conference. One year later,
Hagiwara joined Sony on February 1975 and worked for developping CCD image
sensors at Sony Central Research Center in Yokohama, Japan.

JPG041_Iwama_Kasuo_in_ISSCC1954.jpg



Hagiwara served in various international technical conference committees including ISSCC.

JPG042_ISSCC2003_Executive_Committee_Contribution_Award.jpg



Hagiwara did not publish various important suttle techical items,
but they helped a lot to produce high performance image sensors..

JPG044_Memory_of_Friends_in_Sony_Kumamoto_Tech.jpg



JPG045_Memory_Sony_Kumamoto_tech.jpg



Hagiwara owes so much to Prof. James McCaldin, Prof. T.C. McGill
and Prof.C.A. Mead at California Institute for Technology (Caltech).

Hagiwara studied the bipolar transistor structure and the operational
physics from the Feyman Lecture Book when he was the seoncd year
of his undergradute student life in Caltech, Pasadena in 1968 at age 20.

Hagiwara invented in 1975 the double junction type dynamic photo transistor which was

later called as Pinned Photodiode by Kodak in IEDM1984, and also Hagiwara invented

in 1975 the triple junction type dynamic photo thyristor, which as later called in 1987

as Sony's Hole Accumulation Diode (HAD), the NPNP junction thyristor type photodiode ,

with the punch thru operation
which is applied to achieve the vertical overflow drain

and the electrical shutter functions for fact action movie camera pictures with the

completely image lag free and mecahnical parts free features for the Filmless society.
