Tokuyama Corporation
Notice concerning the Establishment of the Center for Commercialization of Advanced Technology～Working Toward the Commercialization of Silicon Nitride～
Tokuyama Corporation hereinafter referred to as “Tokuyama” or the “Company,” today announced that it
has decided to establish the Center for Commercialization of Advanced Technology with the aim offinding practical application for such advanced materials as silicon nitride.
The Center for Commercialization of Advanced Technology will serve as a base for the development andcommercialization of products that contribute to the protection of the global environment and further
application of ICT. For the foreseeable future, the Center will focus on the commercialization of silicon
nitride for power semiconductor modules used in environmentally friendly automobiles and renewableenergy power generation equipment.
Tokuyama has succeeded in the industrialization of high-purity silicon nitride powder using its proprietarysynthetic technology. The Company has also applied unique technologies to develop an energy-efficient,safe, and low-cost environmentally friendly manufacturing process for plate-shaped ceramics using thishigh-purity silicon nitride powder as a raw material. The Center will begin demonstration tests for themass production of these technologies from fiscal 2021.
Tokuyama is a leading company of aluminum nitride, a major heat dissipation material. Leveraging thetechnologies and abundant experience that the Company has cultivated to date, Tokuyama will contributeto the development of an environmentally friendly and sustainable society by promoting the use of silicon
nitride materials that are both quality and cost.
Comprising mainly manufacturing equipment, an amount of approximately 3 billion yen will be invested
in the Center for Commercialization of Advanced Technology over two-year period. Construction isscheduled to begin in July 2020. Plans are in place for trial operations to begin around April 2021, anddemonstration tests to commence in the summer of 2021 on a progressive basis.

■Silicon Nitride (Si3N4)
With a longstanding history of use, silicon nitride is a type of ceramicmaterial. While powdered materials that are baked and hardened arereferred to as ceramic products, silicon nitride is distinguished by its
thermalconductivity

and

high
