Reports Indicate TSMC to Tighten Scrutiny on Chinese AI Chip Clients; Potential Revenue Impact Between 5% to 8%
November 11, 2024 | TrendForceEstimated reading time: 2 minutes
Reports suggest that TSMC has notified its Chinese clients of a temporary suspension on shipments of advanced AI chips produced using 7nm and below process nodes. Additionally, Chinese clients seeking future advanced process projects will be subject to strict review to ensure the chips are not used for AI or other restricted purposes. TrendForce posits that if the policy takes effect, it could impact TSMC’s revenue performance and utilization rates of its 7nm and below advanced process capacity, while also affecting the future development of China’s AI industry.
The scrutiny follows the revelation that TSMC’s 7nm technology was used in Huawei’s 910B chip. This raised concerns over potential violations of US export regulations, along with allegations that certain companies may have acted as intermediaries to place advanced AI chip orders on behalf of Chinese firms. In response, TSMC is re-evaluating its KYC process and plants to improve its client approval standards, expand product review criteria, and potentially impose additional restrictions on chip size and HBM usage.
TrendForce notes that TSMC is highly likely to implement these measures in the near term, although the full impact will depend on whether the U.S. Department of Commerce issues additional export control regulations or adds specific customers to the Entity List.
For the first three quarters of 2024, TSMC’s revenue distribution shows that advanced nodes accounted for 67% of its total revenue—a key revenue source. However, TrendForce highlights that the major clients for TSMC’s 7/6n, 5/4nm, and 3nm processes are primarily from the U.S., Europe, and Taiwan. Consequently, even if regulatory actions impact business some Chinese clients may be lost, TrendForce expects other customers to offset this loss, limiting the potential effect on advanced process utilization rates.
TSMC’s revenue from China has remained steady at 11% to 13% for the full year of 2023 and the first three quarters of 2024. If regulatory scrutiny of TSMC’s advanced processes intensifies, or if certain Chinese clients are added to the Entity List—particularly affecting Chinese AI-related IC design companies, IP providers, third-party design services, or other businesses that depend on TSMC’s advanced processes for project initiation, tape-outs, and mass production—TSMC could face a revenue impact of approximately 5% to 8%. However, strong global demand for AI chips and TSMC’s planned price increases for advanced process clients are expected to help mitigate some of this impact.

Learning With Leo: UHDI—The Next Leap in PCB Manufacturing
11/05/2025 | Leo Lambert -- Column: Learning With LeoHigh density interconnect (HDI) technology has been a cornerstone of miniaturized electronics since Hewlett-Packard introduced the first chip-scale implementation in 1982. Over time, HDI processes became central to organic flip-chip packaging in the semiconductor industry. Today, the convergence of IC substrates and system-level PCBs has accelerated the adoption of UHDI.
UHDI Fundamentals: UHDI Technology and Automated Inspection
11/03/2025 | Anaya Vardya, American Standard CircuitsFollowing up on the last article on integrating ultra high density interconnect (UHDI) PCB technologies and Quality 5.0, here we will do a deeper dive into the automated inspection component. UHDI applications demand extreme precision, with line/space dimensions below 25 µm and microvias below 30 µm. Automated inspection systems are essential to achieving the defect-free fabrication required at these scales, and legacy automated inspection systems are becoming obsolete and ineffective.
I-Connect007 Editor’s Choice: Five Must-Reads for the Week
10/31/2025 | Nolan Johnson, I-Connect007Last week, the IMPACT conference took place in Taipei, bringing together advanced packaging experts from around the globe to share their knowledge. We’ll be bringing you post-conference coverage over the next few weeks, so look for that in our newsletters, and in the Advanced Electronic Packaging Digest. Other news seemed to have the U.S. at the center of the global discussions. My picks start in Phoenix, where TSMC, NVIDIA, and Amkor are all scrambling to establish new capabilities. There’s nothing like a strong demand signal to cause build-out, and AI chips are doing exactly that.
