The chart is based on data for wafer fab capacities for semiconductor-producing regions worldwide produced by the SEMI industry association. The percentages are derived from monthly wafer starts, normalised to 200 mm wafer equivalents.

The chart shows that all the semiconductor-producing regions excluding China, have declined in the five years from 2015 to 2020.

China went from about 14.4 percent of global production in 1995 to 22.8 percent in 2020.

Europe has fallen from 9.4 percent to 7.2 percent over the same period.  The US is also a relatively small chip manufacturer and provided 10.6 percent of global wafer capacity in 2020, down from 12.6 percent five years before. However, the US government funded campaign to reshore chip manufacturing has stimulated a major fab building exercise by TSMC in Arizona, which together with investment by Samsung and others could reverse this trend.

The world’s second largest regional producer by wafer fab capacity is Taiwan which provides 17.8 percent of global production, down slightly from 18.8 percent in 2020. South Korea is third with 15.3 percent, down from 18.4 percent. The city state of Singapore held 4.7 percent of global chip capacity.
