The future of chipmaking looks more like Manhattan than Silicon Valley
The future of semiconductor manufacturing resembles Manhattan more than Silicon Valley, as chipmaking becomes concentrated in dense, multi-story "megafabs" rather than sprawling horizontal campuses. Rising costs and complexity are pushing production into fewer, capital-intensive facilities built by a shrinking number of companies.
Background
- The global semiconductor industry is undergoing a major strategic shift: countries are moving chip manufacturing from dispersed, efficiency-focused "Silicon Valley"-style clusters to vertically integrated, government-backed "Manhattan Project"-style national efforts.
- This shift is driven by geopolitical tensions (especially US-China tech conflict), supply-chain fragility exposed during COVID, and the astronomical rising cost of cutting-edge fabrication plants (fabs), now exceeding $20 billion each.
- Key players include TSMC (Taiwan), Samsung (South Korea), Intel (US), and SMIC (China), as well as government initiatives like the US CHIPS Act, the European Chips Act, and Japan's Rapidus project.
- The "Manhattan" analogy refers to the US government's WWII atomic bomb program — centrally planned, massive public funding, and secrecy — contrasting with the traditionally market-driven, open-innovation model of Silicon Valley.
- Why it matters: Chips underpin everything from smartphones to AI, military systems, and electric vehicles. Who controls advanced chipmaking increasingly determines technological sovereignty and economic power.
