AGC Inc.(AGC), a world-leading manufacturer of glass, chemicals and high-tech materials, has accepted a portion of a third-party allocation of new shares issued on February 21 by Novel Crystal Technology, Inc. (NCT), a company engaged in developing a next-generation power semiconductor material.

 

Power semiconductors are electronic components that function to control electric power. They are found in a wide range of electric and electronic devices such as servers, automobiles, industrial machinery, and home appliances. Since the performance of power semiconductors directly impact the energy saving, weight reduction and miniaturization of power control modules, the performance requirements for these devices is increasing year by year. As such there is a need for semiconductor materials with lower power loss and superior voltage resistance and large current characteristics compared to silicon, the conventional material.

 

Gallium oxide is a next-generation power semiconductor material with a power semiconductor figure of merit of more than 3,000 times that of silicon. It is also attracting considerable attention because it has the potential to be used at even higher voltages and currents than other materials being explored, such as SiC (silicon carbide) and GaN (gallium nitride).

 

To date, NCT has succeeded in developing, manufacturing, and selling gallium oxide wafers of up to 100mm, and has a global share of nearly 100%. AGC has been working on joint development and investing in NCT since 2018, based on the idea that NCT's high technology and AGC's inorganic material mass-production technologies, such as high-temperature melting, polishing processing, and cleaning cultivated through glass manufacturing, would enable mass production of gallium oxide at an early stage. With this third follow-on investment, AGC and NCT will further accelerate their activities toward the commercialization of gallium oxide wafers by 2023.

 

Under its AGC plus 2.0 management policy, the AGC Group has positioned Electronics as one of its strategic businesses. AGC will continue making aggressive development efforts and investment in semiconductor-related business, which is expected to continued significant growth in demand, and thus contribute to the advancement of the semiconductor industry.
