US senators flag Intel tests with China-linked ACM chipmaker

A bipartisan group of US lawmakers led by Elizabeth Warren and Tom Cotton, both senators, raised national security concerns over Intel’s testing of chipmaking tools from ACM Research, a Fremont, California-based equipment maker with deep roots in China and two overseas units targeted by US sanctions.

In a letter to Lip-Bu Tan, Intel CEO, the lawmakers said ACM’s access to Intel facilities could expose cutting-edge chipmaking processes that may materially improve the competitiveness of ACM and Chinese military companies.

The letter was signed by Elizabeth Warren and Tom Cotton, as well as Elissa Slotkin, Andy Kim, Jim Banks, and Pete Ricketts.

Intel said ACM tools are not used in its semiconductor production processes and that it complies with US laws and regularly engages with the US government.

The lawmakers noted the US government now owns a stake in Intel, raising fiduciary concerns.

Reuters said ACM did not immediately respond to a request for comment; the company previously said it could not discuss specific customer engagements but confirmed its US team has sold and delivered multiple tools from its Asian operations to domestic customers.

ACM also disclosed shipment of three tools to a “major US-based semiconductor manufacturer,” which are being tested and some have met performance standards.

🧠 Food for thought

Implications, context, and why it matters.

The government’s stake in Intel adds weight to security concerns

The lawmakers’ letter carries extra weight because the U.S. government regulates Intel and also holds a stake in the company.
Lawmakers warned that ACM access to Intel sites could reveal advanced chipmaking methods that could meaningfully boost ACM and Chinese military-linked firms.
They also flagged that ACM Research, a Fremont, California-based chipmaking equipment maker with deep roots in China, has two overseas units targeted by U.S. sanctions.
That leaves Intel in a tight spot while it evaluates chipmaking tools from a supplier tied to China and linked to sanctioned overseas units.

CHIPS Act funding can turn supplier decisions into geopolitical tests

Closer review of Intel’s vendor choices could discourage equipment makers, especially those with large China business, from pursuing CHIPS Act funded customers.
Companies with deep China ties, including U.S.-based firms like ACM Research, may face tougher screening when selling to CHIPS Act recipients.
Intel said ACM tools are not used in its semiconductor production processes, it follows U.S. laws, and it stays in regular contact with the U.S. government.
Lawmakers raised fiduciary concerns for Intel’s leadership and board.
