US-based fabs, or chip manufacturing plants, currently only account for 12% of the world’s modern semiconductor manufacturing capacity, according to data from the Semiconductor Industry Association trade group. Some 75% of the world’s modern chip manufacturing is now concentrated in East Asia – a majority of that in geopolitically-vulnerable Taiwan. Now, simply having the facilities already set up to produce or expand chip manufacturing gives Asia a big advantage. This is not yet the case in places like Arizona and Ohio, where plans to build massive chip manufacturing plants are already underway. If not, even the billions of dollars committed by the private and public sector may not be enough to reshore semiconductor manufacturing.
