Presentation by Dr. Mitsu Koyanagi
A new three-dimensional (3D) integration technology is discussed. This technology allows us to stack various kinds of known good dies with different die sizes which are fabricated using different technologies. We have developed six key element technologies for this new 3D integration technology. In addition, 3D image sensor chip and 3D memory chip were fabricated using this 3D integration technology.

Biography
Mitsu Koyanagi received the B.S. degree from Dept. of Electrical Engineering,
Muroran Institute of Technology, Japan in 1969 and the M.S. and Ph.D. degrees
from Dept. of Electronic Engineering, Tohoku University in 1971 and 1974,
respectively. He joined the Central Research Laboratory, Hitachi Co. Ltd.
in 1974 where he had engaged in the research and development of DRAM and
ASIC process and device technologies and invented a Stacked Capacitor DRAM
memory cell which has been widely used in the DRAM production. In 1985,
he joined Xerox Palo Alto Research Center, California where he was responsible
for the research of submicron CMOS devices, poly-Si TFT devices and analog/digital
sensor LSI design. He became a professor in Research Center for Integrated
Systems, Hiroshima University, Japan where he engaged in the research of
sub-0.1um device fabrication and characterization, device modeling, optical
interconnection and parallel computer system. Since 1994, he has been a
processor in Intelligent System Design Lab., Dept. of Machine Intelligent
and Systems Engineering, and currently Dept. of Bioengineering and Robotics,
Graduate School of Engineering, Tohoku University, Japan where his current
interests are three-dimensional integration technology, optical interconnection,
nano-devices, memory devices, low voltage and low power integrated circuits,
new intelligent memory for parallel processor system, parallel computer
system specific for scientific computation, real-time image processing
system and artificial retina chip, bio-chip, brain-like computer system.
He was a director of Venture Business Laboratory, Tohoku University from
1998 (May) to 2000 (May). He was awarded IEEE Cledo Brunetti Award in 1996
and Award of Ministry of Education, Culture, Sports, Science and Technology
in 2002 in addition to Ohkouchi Prize in 1992, SSDM (Solid-State Devices
and Materials Conf.) Award in 1994 and Opto-Electronic Integration Technology
Award (Izuo Hayashi Award) in 2004. He has been an IEEE fellow since 1997.
He has published more than 200 papers and is the author or the co-authors
of several books such as "Physics of VLSI devices", "Submicron
Devices I & II" etc.
