News Release

JX Advanced Metals Corporation (President: Hayashi Yoichi; hereinafter "the Company") hereby announces its investment in Rapidus Corporation (Representative Director and CEO: Koike Atsuyoshi, PhD in Engineering; hereinafter "Rapidus"), participating in the chipmaker's large-scale funding round designed to finance mass production of state-of-the-art logic semiconductor devices.¹

　

Rapidus engages in research, development, and manufacturing to mass-produce cutting-edge logic semiconductor devices, an electronic component crucial for next-generation industries such as AI data centers, robotics, and high-speed communications. By supplying domestically produced highest-end logic semiconductor devices, it aims to help enhance the resilience and competitiveness of Japan's semiconductor industry and contribute to global industrial development. Through collaboration with its partners including advanced research institutions overseas, Rapidus is working to put the most advanced technology into practical applications and build mass-production capacity. It plans to start the mass production of 2 nm-generation logic semiconductor devices in 2027. 

　

In recent years, as technological innovation accelerates as seen in the development of generative AI, there is strong demand for semiconductor devices capable of higher performance with lower electricity consumption, resulting in ever more complex manufacturing processes. Accordingly, cooperation with a wide range of partners, including those with expertise in materials, design, and apparatus engineering, is becoming indispensable.

　

The Company has supported the endeavors of Rapidus up until now through the supply of various types of semiconductor materials such as semiconductor sputtering targets, in which we have a global top market share. With our investment this time, we will further deepen our partnership with Rapidus and, under a cooperative framework that goes beyond a customer-and-supplier relation, pursue improved technological capabilities in semiconductor front-end and back-end processes² and in the recycling of scraps, effluent, etc. Furthermore, in the formation of a new semiconductor ecosystem centered on Rapidus, we plan to bolster our cooperation with companies in the semiconductor field to gain insight and opportunities conducive to our future business development. Capitalizing on technological innovation and changes in market structure, we will actively pursue joint development, supply chain collaboration, and partnerships that will give birth to new businesses. Through these endeavors, we will explore technological and market opportunities that will lead to further expansion of our semiconductor business and value creation.

Moreover, we will utilize our new Chitose office (Chitose City, Hokkaido)³ to strengthen our local information-gathering and sales activities for deeper and faster development of our products, thus gaining even stronger competitiveness. 

　

Going forward, we will continue to actively pursue product and technology development through co-creation with our partners. By proposing and providing innovative advanced materials, we will contribute to the realization of a sustainable society.
