An agreement between the United States, Japan and the Netherlands to restrict exports of “some” advanced chip-making equipment to China has triggered debate over the scale of damage that this could inflict on Beijing’s semiconductor self-sufficiency drive, with billions of dollars of investments at stake.
That deal was reached in talks that concluded in Washington on Friday, creating a powerful alliance that will undercut Beijing’s ambitions to build its own domestic chip capabilities, according to a Bloomberg report, which cited people familiar with the negotiations.
Details of that pact, however, remain unknown. There is no plan for a public announcement of the restrictions, and actual implementation could take months as Tokyo and Amsterdam finalise legal arrangements, according to the report.
Chinese Foreign Ministry spokeswoman Mao Ning said on Monday at a briefing that the US-led agreement is not only harmful to all concerned parties, but threatens the stability of the global semiconductor supply chain.

A Naura Technology Group executive, who declined to be named, said the new alliance presents a significant escalation from unilateral US export controls, especially if any of the 28-nanometre lithography process equipment in the market were included in the ban. Naura is China’s top semiconductor manufacturing equipment maker.
Commercial chip manufacturing using 28-nm process machinery started in 2011. 28-nm chips are used on a wide range of applications, including central processing units, graphics processors, high-speed networking chips, and integrated circuits that power smartphones, tablets and other consumer electronics devices.
So-called ultraviolet lithography equipment, which uses laser technology to basically carve a pre-designed circuit onto a wafer, is at the centre of the joint export control pact, according to a report authored by Jefferies analyst Edison Lee on Monday.
Dutch firm ASML Holding dominates this market, with a nearly 90 per cent share on the back of its highly advanced extreme ultraviolet (EUV) machines. “EUV is a must for 5-nm semiconductor technology or below, and the Netherlands agreed not to sell EUVs to China since 2019,” Lee said.
EU joins US in ‘depriving China of the most advanced chips’, official says
ASML confirmed in a statement on Sunday that the scope of agreed export controls could go beyond advanced lithography technology. Before export controls come into effect, “it has to be detailed out and implemented into legislation which will take time”, the company said.
Alternative lithography equipment vendors are Japan’s Nikon Corp and Canon, which make less-advanced deep ultraviolet (DUV) systems. There are several versions of DUV, and the most advanced one is called ArF Immersion DUV, which enables chip technology processing nodes between 45-nm and 7-nm.
If ArF Immersion DUVs become 100 per cent restricted from being sold to China, mainland chip foundries such as Semiconductor Manufacturing International Corp, Hua Hong Semiconductor, Shanghai Huali Microelectronics Corp and ChangXin Memory Technologies “would have trouble expanding capacity in even mature nodes” like 28-nm, Jefferies’ Lee said.

He indicated that if the ban applies only to 14-nm or below chip-processing technology, “it may be hard to enforce since tracking what the machine is used for over time is challenging”.
Echoing that comment, Nicolas Gaudois, head of Asia-Pacific technology research at UBS, said: “It is quite hard for the equipment companies to show that the equipment being shipped is actually not [falling] in the scope of [restrictions].”
Speculation about the US-Japan-Netherlands pact reflects intensifying uncertainty for China’s semiconductor ambitions, months after the Biden administration implemented updates that further restrict China’s ability to obtain advanced chips, develop and maintain supercomputers, and manufacture advanced semiconductors.

“We believe the lack of official announcements and details could mean that Japan and the Netherlands have agreed only in principle, but not yet to the details,” Jefferies Lee said. “The biggest sticking point is likely what kind of lithographic machine should be restricted.”
Further restrictions on DUV equipment could limit China’s output in mature chip technologies, according to Arisa Liu, a senior semiconductor research fellow at the Taiwan Institute of Economic Research.
Still, China’s imports of lithographic machines rose to about US$4 billion in 2022, up from US$1.3 billion in 2017, according to the Jefferies report. It said import statistics show that China has increasingly relied on Japanese vendors, with lithographic machine imports from them growing to 33 per cent in last year from 27 per cent in 2017.
