➀ Japan leads in three out of five categories of new 'semiconductor materials', with some categories seeing Japanese companies hold a 100% market share. Experts warn that Chinese and South Korean companies are gaining influence in the semiconductor materials field, with China pushing for domestication, potentially reducing Japanese market share. ➁ The Nikkei 2023 'Major Products and Services Market Share Survey' shows that Japanese companies rank first in 10 categories, an increase of 4 from the previous survey. In the new 'semiconductor materials' category, Japanese companies are first in three categories. ➂ Tokyo Ohka Chemical is the leading player in photoresist with a 22.8% market share, excelling in traditional automotive products and EUV photoresist for the latest smartphones. The company has strengthened production and sales systems in Kagoshima and North America, with a sales target for the fiscal year ending December 2030 set at 350 billion yen, 1.7 times higher than the original plan. ➃ Shin-Etsu Chemical has the highest global market share in silicon wafers, with 24.7%, and is the only company, along with Sumco, that can produce the most advanced products. ➄ In the Mask Blanks category, three Japanese companies dominate the global market share, with HOYA holding over 60% of the market share.
