Spherical silica is used as a filler for semiconductor sealant. As the scope of semiconductor applications has expanded over the past few years, demands regarding the quality of spherical silica have been increasing. The traditional manufacturing method carries a risk of carbon contamination from fossil fuels, which impairs insulating performance and reduces the reliability of the semiconductor. In February 2022, Taiyo Nippon Sanso Corporation and Admatechs Company Limited developed a melting and spheroidizing technology using carbon-free ammonia-oxygen combustion to enable the production of high-quality spherical silica free from carbon contamination.
