U.S. investigates TSMC on chip dealings with Huawei

U.S. is suspecting TSMC over chip dealings with Huawei. The authorities have reportedly begun investigating the Taiwanese semiconductor firm to determine if it has supplied any smartphone or AI chipsets to the Chinese tech giant.

The U.S. is looking for every loophole that can help Huawei in the advanced chipmaking process. A recent report said that the Biden administration may soon add more Chinese firms to the Entity list, blocking the growth of the chip network in China.

Apart from keeping an eye on China, the U.S. is now investigating other foreign suppliers who can lend a hand to Huawei in semiconductor manufacturing.

Inputs reveal that the U.S. Commerce Department started probing TSMC for chip dealings with Huawei. The investigation is in the early stages and aims to check if the chipmaker has been making any AI or phone chips for Huawei for the time being.

If TSMC is found breaching the U.S. export regulations, it might face huge penalties or even a prohibition on using advanced chipmaking tools or techs temporarily.

Under this investigation, the U.S. authorities have targeted the Mate 60 series’ Kirin 5G 9000s chip and recently developed AI Ascend processor. Both these chipsets significantly contribute to China’s progress in the semiconductor industry.

The Commerce Department inquired TSMC about having any direct or indirect (via different names) chip shipments to Huawei in the past or at present. Investigators are also looking into other related aspects like “know-your-customer checks”.

Issues for TSMC

Further details note that the investigation could trouble TSMC to some extent. The Taiwanese chipmaker is one of the key chipset suppliers for U.S. firms.

For instance, Apple and Nvidia mainly rely on TSMC for their processors. Also, the Biden administration was planning a $6.6 billion subsidy for the chipmaker to develop its third fabrication unit in Arizona. However, an investigation could halt benefits for some time.

TSMC responded to this investigation and said that it follows all the U.S. export regulations without fail. Although if there is a problem, then it will take action to guarantee compliance in all possible aspects.

“TSMC is a law-abiding company and we are committed to complying with all applicable regulations. If we have any reason to believe there are issues, we will take prompt action to ensure compliance.”

HuaweiCentral’s Take

The U.S. will try every effort to push back Huawei as done in 2019. But this time, the Chinese OEM is focusing on being self-reliant. A recent report claimed that Huawei Kirin 7nm chip performance can match the level of the 5nm processor of TSMC.

How far the U.S. will stretch this investigation on TSMC chip dealings with Huawei would be worth looking forward to.
