- Stable Production Technology Established for
Difficult-to-produce High-purity "Yttrium Iron Garnet" Single
Crystal -
TOKYO and SAKU, Japan, Aug. 19,
2024 /PRNewswire/ -- Carlit Co., Ltd., based in Tokyo, announced on August 19 that its consolidated subsidiary
Silicon Technology Corporation (hereinafter referred to as "Silicon
Technology") has established a stable technology to produce
high-purity, high-quality yttrium iron garnet (Y3Fe5O12,
hereinafter "YIG") single crystals, and has entered the
magneto-optical material business.

Since its establishment in 1995 in Saku City, Nagano Prefecture, Japan, Silicon Technology has been engaged in
the integrated production of silicon materials for semiconductors,
from the growth of silicon single crystal using the CZ pulling
method to mirror wafer processing and cleaning, at its own
facilities. The company also produces silicon materials in an
integrated manner. Utilizing these silicon single-crystal growth
technologies, Silicon Technology is now expanding its business into
the field of magneto-optical materials.
1. About Magneto-optical Material "YIG"
YIG is garnet-type ferrite crystal with magnetic properties, and
has excellent optical and microwave properties. Single crystals
called magneto-optical materials, typified by YIG, are used in
communications equipment such as isolators and circulators.
It is indispensable for faster communication speeds and
increased information volume in the current information society,
for instance for the 5G wireless communications technology, which
is now becoming widespread for the development of next-generation
6G communications. The 6G network is expected to expand to all
locations, including sea, air and space in addition to land, and is
likely to be an area for market growth in the future.
2. Background of Entry into Magneto-optical Materials Field
As an indispensable material for the progress of the information
society, YIG single crystals are in demand for their high quality
and stable performance. However, YIG single crystals require
establishment of a stable production technology and the maintenance
of high quality, which are extremely difficult. The floating zone
(FZ) method was developed for the growth of YIG single crystals.
The production of high-purity single crystals has now become
possible by Silicon Technology's proprietary process, and the
company has successfully established and commercialized an
integrated process from the generation of a YIG single crystal to
wafer fabrication, similar to that used for silicon wafer
products.
3. Future Prospects
Silicon Technology will merge with Carlit Co., Ltd., effective
October 1, 2024. Based on the
strength of its single-crystal growth technology and integrated
production process up to wafer fabrication, the company is
considering developing services such as prototype development of
single-crystal materials and contract melting of crystal materials,
in addition to single-crystal sales. It will continue to improve
its technological capabilities by responding to various needs and
requests without being bound by the framework of semiconductor and
magneto-optical materials.
The Carlit Group will continue contributing to the development
of cutting-edge technologies in Japan under the slogan, "To contribute to a
sustainable society by combining the power of 'chemistry' and
'technology' to support people's happy lives."
