TAIPEI, Taiwan: Taiwanese chipmaking giant TSMC halted shipments to a customer this month after its semiconductors were sent to China’s Huawei, a Taipei government official told AFP, potentially breaching US sanctions.
Taiwan Semiconductor Manufacturing Company is the world’s largest contract manufacturer of chips that are used in everything from Apple’s iPhones to Nvidia’s cutting-edge artificial intelligence hardware.
Huawei, the world’s leading equipment maker for fifth generation mobile internet networks, has been embroiled in a tech war between Beijing and Washington.
The United States slapped sanctions on Huawei in 2019, and expanded them the following year, claiming its technology could be used for Beijing’s espionage operations. Huawei denies the allegations.
The sanctions cut Huawei off from global supply chains that gave it access to US-made components and technologies.
TSMC discovered on October 11 that chips made for a “specific customer” had ended up with Huawei, the Taiwanese official with knowledge of the incident told AFP on the condition of anonymity.
TSMC “immediately activated its export control procedures”, halting shipments to the customer and notifying US and Taiwan authorities, the official said.
In a statement on Wednesday, TSMC said it was a “law-abiding company” and had not supplied Huawei since mid-September 2020 in compliance with export controls.
“We proactively communicated with the US Commerce Department regarding the matter in the report,” TSMC said, apparently referring to media reporting of the incident.
“We are not aware of TSMC being the subject of any investigation at this time.”
Taiwan’s economic ministry told AFP on Thursday that TSMC had informed them about the incident, but had not identified their client.
“There was already an interaction and a contractual partnership in place, so it’s an old client,” the ministry said.
“No shipments have been made since October 11.”
Bloomberg reported Tuesday that Canadian research firm TechInsights had found an advanced processor made by TSMC inside Huawei’s latest AI chip.
Huawei did not respond to AFP’s request for comment.
The company told Bloomberg that it hadn’t “produced any chips via TSMC after the implementation of the amendments made by the US Department of Commerce” to its trade restrictions targeting Huawei in 2020.
