Japan is a global powerhouse in the integrated circuit industry area，but in recent years，Japan’s integrated circuit industry is shrinking in size. In 2018，Japan’s integrated circuit market accounted for only 6.9% in the global integrated circuit market，which was almost the same as 2017. Japan’s monopoly position in the field of semiconductor materials can not be shaken. In 2018，the market share of silicon wafer and masks are accounted for far more than 50% of the global total market；Japan’s equipment supply capacity leads the world’s top three in the integrated circuit equipment market，further more，among the world’s top 10 equipment companies，Japan occupied 5 seats；In 2018，the main application market of Japanese integrated circuits were in the field of computers and communications，accounting for more than half of the total；Manufacturing capacity is still strong，and domestic market supply exceeds demand. As Japan’s capital investment in the integrated circuit industry climbs year by year，the competitiveness of the integrated circuit industry cannot be underestimated.
