Hudson Institute Report Argues US and Allied Semiconductor Equipment Concentration Provides Critical Leverage Over China's Chip Ambitions

BLUFAllied leverage over China's chip ambitions rests on a narrow set of chokepoints that will erode without coordinated export controls and sustained toolmaker investment, yet Washington has adopted neither step.

A Hudson Institute report by Jason Hsu, Heberto Limas, and Chris Gorin, published November 11, says chipmaking toolmakers are concentrated in the United States, Japan, the Netherlands, and a Hong Kong-Singapore cluster, with ASML holding what the authors call arguably a true monopoly in EUV lithography 1. The report states China can equip a mature-node fab almost entirely from domestic suppliers but retains gaps in leading-edge capabilities 1. It cites VAT's roughly 58 percent share of vacuum valves and KLA's majority share of inspection and metrology as concentration points 1. The authors recommend prioritizing technology development over delaying Chinese access, harmonizing allied controls, and exempting tools from tariffs 1. An aggregator repost carried the same report without added reporting 2.

Analysis
The report treats allied control of chipmaking tools as a wasting advantage. Because China already equips mature-node fabs almost entirely domestically, export controls now bite mainly on leading-edge gaps in inspection, metrology, and EUV, and the nearer-term risk is Chinese displacement of Western toolmakers in China and third markets rather than a leap to the frontier. Concentration also cuts both ways, since single points of failure like vacuum valves and Zeiss optics expose allied firms as well. Its recommendations rest on US policy levers: harmonized Dutch and Japanese controls, a standing tariff exemption, and field-engineer visas, giving Congress and Commerce a ready agenda. Confidence is low, because this is a single think-tank report with uncorroborated market-share figures and no policy response yet. The report may also be advocacy for tariff exemptions and CHIPS follow-on funding, overstating erosion risk to support those requests.
