As a percent of worldwide total, China achieves largest increase in fab capacity at expense of all other regions, but still trails Taiwan, South Korea, and Japan in installed capacity.

IC Insights’ Global Wafer Capacity 2021-2025 report breaks out the world’s installed monthly wafer capacity by geographic region (or country).  Figure 1 shows the installed capacity by region as of December of 2020.

To clarify what the data represents, each regional number is the total installed monthly capacity of fabs located in that region regardless of the headquarters location for the companies that own the fabs.  For example, the wafer capacity that South Korea-based Samsung has installed in the U.S. is counted in the North America capacity total, not in the South Korea capacity total.  The ROW “region” consists primarily of Singapore, Israel, and Malaysia, but also includes countries/regions such as Russia, Belarus, and Australia.
