The US and the Netherlands are set to deliver a one-two punch to China’s chip makers soon by further restricting sales of chip-making equipment, part of the countries’ ongoing effort to prevent their technology from being used to strengthen China’s military.
While the Dutch are planning to curb certain equipment from national champion ASML, and other companies, the US is expected to go one step further and use its long reach to withhold even more Dutch equipment from specific Chinese fabs.
The Dutch government and ASML declined to comment, as did the US commerce department, which oversees export controls.
The US in October imposed export restrictions on shipments of American chip-making tools to China from US companies like Lam Research and Applied Materials on national security grounds, and lobbied other countries with key suppliers to adopt similar curbs.
Chinese embassy spokesman Liu Pengyu in Washington decried the move and said the US “has deliberately blockaded and hobbled Chinese companies and forcibly relocated industries and pushed for decoupling”, and said China would “closely follow the developments and firmly safeguard our own interests”.
Japan, home to chip equipment makers Nikon and Tokyo Electron, has since adopted rules to restrict exports of 23 types of semiconductor manufacturing equipment that will take effect on 23 July.
The Dutch government plans to announce new regulations on Friday with a licensing requirement for the top tier of ASML’S second-best product line, deep ultraviolet (DUV) semiconductor equipment. ASML’s most sophisticated machines — extreme ultraviolent “EUV” lithography machines — are already restricted, and have never been shipped to China.
DUV models
ASML said in March it expects the Dutch regulations to affect its Twinscan NXT:2000i and more sophisticated models. But the company’s older DUV models, like one called the Twinscan NXT:1980Di, could also be kept from about six Chinese facilities by the US. The facilities are expected to be identified in a new US rule that will allow the US to restrict foreign equipment with even a small percentage of US parts to those sites, according to a person familiar with the matter. The person was not authorised to speak publicly.
The new Dutch regulations will not take effect immediately, sources said, with one person expecting the effective date to be September, two months after publication.
The planned US rule, which sources said may be published by in late July, will require licences to export equipment to about half a dozen Chinese facilities, including a fab operated by SMIC, China’s largest chip maker, the person familiar with the US plans said. Licences to ship the equipment to those facilities will likely be denied, the person said.
The US rule is expected to apply to ASML, the world’s leading chip equipment maker and Netherlands’ largest company, because its systems contain US parts and components.
It is not unusual for the US to modify proposals before clearing regulations, so both the timing and the restrictions could change. The plan described reflects thinking in late June. The US is also expected to come out with other updates to its sweeping October rules in July, according to sources.
ASML is Europe’s largest chip equipment company due to its dominance in lithography, one of the central steps in the computer chip-making process.
Other companies that could be impacted by the new Dutch rules include atomic layer deposition firm ASM International. A spokesman for the Almere-based company declined comment ahead of Friday’s announcement. — Karen Freifeld, with Toby Sterling, (c) 2023 Reuters
