Taiyo Nippon Sanso Corporation (TNSC) has developed an inorganic powder melting and spheroidizing technology that can contribute to the achievement of carbon neutrality in the semiconductor materials manufacturing process. The technology combines the CERAMELT® powder melting and spheroidizing system, which uses pure oxygen combustion, with hydrogen combustion technology. Spherical particles are used as resin filler for semiconductor sealant, and so forth, contributing significantly to performance increase and miniaturization of semiconductors. With the recent expansion of semiconductor use, requirements for reducing the environmental impact of the manufacturing process have become more demanding. This technology developed by TNSC uses hydrogen as the fuel, thus reducing CO₂ emissions in the exhaust gas to zero. This greatly contributes to the reduction of environmental impact in the manufacturing process, while also contributing to the manufacturing of high-quality spherical particles with reduced carbon impurities.
