TSMC could end up paying $1 billion or more to settle a US investigation into whether the Taiwanese outfit busted sanctions by indirectly producing AI accelerators for America's bête noire / hēi yáng, Huawei.
Citing two unnamed persons said to be familiar with the matter, Reuters on Tuesday reported the penalty could amount to as much as twice the value of transactions between TSMC and Chinese chip designer Sophgo last year.
As you may recall, Sophgo was accused in late 2024 of acting as a front for Huawei, allegedly allowing the networking equipment giant to side-step US sanctions and acquire advanced semiconductors that should have been off limits. Specifically, TSMC grew suspicious after Sophgo placed orders for a chip closely resembling Huawei's Ascend 910B AI accelerator, and raised the alarm to Uncle Sam.
As we've previously reported, the Ascend 910B is among Huawei's most-sophisticated processors, boasting performance roughly on par with a now five-year-old Nvidia A100, with 320 teraFLOPS of FP16 performance.
TSMC had previously produced silicon for Huawei's chips, including the Ascend series, up until the Chinese telecommunications titan found itself on the US Entities List in 2019. Being on that list means you can't do business with or using American organizations and technologies without special permission from Uncle Sam, simply put.
Because TSMC relies on US tech to produce its chips, these export controls extended to Taiwanese fabs, and meant that as of 2020 Huawei could no longer source silicon from the foundry giant without permission from the United States.
These controls didn't however apply to Sophgo, a fabless chip designer specializing in the RISC-V instruction set, which denied allegations of sanctions busting. However, US officials weren't buying it and earlier this year Sophgo joined Huawei on the Entities List.
Despite blowing the whistle on the alleged shenanigans, it seems the Trump administration nonetheless intends to extract penalties from TSMC. This is despite the company's plans to expand US fab production to the tune of $100 billion, announced by CEP CC Wei alongside US President Donald Trump last month.
The reported penalties may be part of a broader crackdown by the US Bureau of Industry and Security on export violations.
"We will not allow adversaries to exploit American technology to bolster their own militaries and threaten American lives," US Commerce Secretary Howard Lutnick said last month as part of another round of restrictions on AI exports. "We are committed to using every tool at the Department's disposal to ensure our most advanced technologies stay out of the hands of those who seek to harm Americans."
