Semiconductors are one of the foundations of any modern economy. They’re used in everything from home appliances to automobiles to weapon systems. During the Covid-19 pandemic, however, they suddenly became very hard to acquire. Production of semiconductor chips is concentrated in Taiwan and South Korea, and disruptions to global supply chains meant U.S. companies faced year-long waits for chips. This past summer, Commerce Secretary Gina Raimondo warned that an inability to access Taiwan’s semiconductors would lead the U.S. to a “deep and immediate recession.” In other words, dependency on foreign production is a national security risk for the United States.
