The United States has escalated its oversight of China’s foremost sanctioned semiconductor manufacturer, SMIC, by implementing additional restrictions on American imports to its premier facility. This action comes in response to the factory’s developing a sophisticated chip designed for Huawei’s Mate 60 Pro smartphone.
In the latter part of the previous year, the Commerce Department issued numerous notifications to U.S. suppliers of SMIC, particularly targeting its most sophisticated plant, suspending their sales permissions. As informed by individuals requesting anonymity due to unauthorized public discussion, this directive effectively ceased multimillion-dollar transactions in chip manufacturing components and materials to SMIC South from companies including Entegris.
Entegris, while not found in violation of U.S. laws, confirmed compliance with a valid export license before ceasing shipments post-Commerce Department notifications. The company, specializing in semiconductor manufacturing essentials, highlighted its adherence to complex international trade regulations impacting the chip sector.
Responses from SMIC and Huawei were unavailable, and the White House and the Commerce Department abstained from commenting. A Chinese embassy spokesperson criticized the U.S. actions as economic coercion, cautioning against the misuse of national security as a pretext to suppress Chinese firms.
These license suspensions underscore the Biden administration’s efforts to limit SMIC’s access to U.S. technology amid increasing demands from critics urging a tighter clampdown. This development follows the unveiling of Huawei’s Mate 60 Pro, equipped with China’s most advanced semiconductor, challenging U.S. restrictions to curtail China’s high-tech capabilities.
Despite the new measures, critics, including Republican Congressman Michael McCaul, argue that the Commerce Department’s actions are insufficient and belated, casting doubts on the agency’s commitment to national security.
The path towards tightening restrictions on SMIC and Huawei has been gradual. Both companies faced U.S. trade bans under allegations of sanction violations and connections to China’s military, which they denied. Although initially allowed certain transactions, the Biden administration’s October 2022 regulations significantly narrowed U.S. technology exports to advanced Chinese chip facilities, including SMIC South.
Entegris’ contributions to SMIC South until the end of the prior year underscore the impact of U.S. export controls on American firms operating in China. With China constituting a significant portion of Entegris’ revenue, the company acknowledges the potential for further demand reductions due to U.S. policies.
Industry experts suggest that SMIC South, critical for producing Huawei’s advanced 7-nanometer chip, may face operational disruptions without U.S. supplies, potentially halting production temporarily. This analysis aligns with insights revealing SMIC’s exclusive capability within its operations to manufacture the sophisticated processor found in the Mate 60 Pro.
The ongoing developments reflect the intricate balance of global semiconductor supply chains, national security interests, and international trade regulations, highlighting the broader implications of U.S. policy shifts on the tech industry.
