The persistent global shortage of semiconductors has prompted governments and chip manufacturers around the world to take actions to expand production and prevent such shortages from occurring again. But in formulating their plans, they should include measures to ensure that future supply chains for computer chips are resilient. A study that we conducted with DENSO, a global automotive component manufacturer whose headquarters are in Japan, highlighted how vulnerable the semiconductor supply chain is to disruptions. We found that a short disruption of a semiconductor fabrication facility, or “fab,” in Taiwan for 10 days, could cause a flurry of additional disruptions across the entire supply chain that would last almost a year.
