Currently, only a handful of countries are capable of producing 1-nanometer (nm) chips, including the United States, China, South Korea, Japan and Europe. This is because the production of 1nm chips requires an extremely high level of technology and equipment investment, and these countries have advanced technology and capital resources to bear such production costs.
In addition, these countries are also staying ahead of the competition, investing in research and innovation, and improving production efficiency and quality. As a result, these countries are able to occupy a larger share of the global market and drive technological progress and industrial development.
