Huawei's 5nm Chip Just Made TSMC's 2nm Chips Look Like a JOKE!

Overview

The video argues that Huawei—working through SMIC and collaborating teams—has effectively undermined the export-control strategy intended to halt China’s progress in advanced chipmaking. The central point is that China can reportedly reach “5nm-level” chip density without access to the most restricted fabrication tools, especially EUV lithography.

Key Claims and Evidence

• TSMC’s “2nm” advantage is being challenged. The video claims Huawei’s Kirin 9030 (a 5nm-class chip in Huawei’s latest flagship phones) shows that TSMC’s manufacturing lead is shrinking faster than Washington expected.

• Teardowns suggest Kirin 9030 used legacy-era equipment. TechInsights disassembled the chip and concluded it was manufactured by SMIC using a process SMIC calls N+3—described as the most advanced Chinese commercial production to date.

• Independent lab confirmation (density metrics). A second lab reportedly validated similar conclusions using transistor/wiring density figures, such as:

  • ~113 million transistors per square millimeter
  • wire density comparisons The video claims the density is comparable to TSMC’s older nodes, even without access to top-end tooling.

How China Allegedly Did It Without the “Thin Handle”

The video frames lithography restrictions as a “thin handle” constraint: without EUV scanners, China was expected to stall around ~7nm.

Instead, it argues China used a “thick marker” strategy:

• Multilayer patterning / multiple exposures using existing DUV tools (i.e., older, less precise printing).

• Design–process co-optimization where chip designers and factory engineers redesign layouts to better match what legacy equipment can reliably print.

The video further claims that SMIC can use up to four printing/etch cycles per dense layer and achieves unusually tight metal pitch in the Kirin 9030.

Industrialization Hurdles and Cost/Yield Realities

The video acknowledges the approach is harder and more expensive than leading-edge EUV manufacturing:

• Yield is the bottleneck (how many chips work per wafer).
• It cites external analyst estimates claiming SMIC yields are far lower than TSMC’s for mature leading-edge processes.
• It also claims pricing is significantly higher (e.g., ~50% higher). However, it argues Huawei’s business model—selling full devices with its broader software ecosystem—can make those costs more manageable.

Broader Implications: The “Wall” Is Cracking Beyond SMIC

The video argues the most concerning outcome for the U.S. is that advanced know-how may spread to other factories, reducing the leverage of export controls.

• It references reporting that Huahong (Huawei’s supply-chain ecosystem, via collaboration with Huawei Microelectronics) is preparing to produce 7nm chips at a Shanghai facility.
• The claim is that this relies on similar general know-how/approach, supported by Chinese equipment testing efforts.
• It also argues this creates additional customer pathways (including mention of Biren), enabling more AI and advanced-computing projects to move from demos to mass production.

Link to AI Accelerators and Competitive Pressure

The video shifts from phones to AI, arguing that manufacturing techniques learned at 7nm / “5nm-class” levels for mobile chips can apply to AI accelerator chips—including Huawei’s Ascend (presented as a reported alternative to Nvidia).

The conclusion: once multilayer and legacy-process mastery scales, China can steadily close performance gaps across broader segments of compute.

Where TSMC Fits In (and What the Video Says Has Changed)

The video describes TSMC’s “2nm” progress as dependent on:

• EUV lithography, and
• Gate-all-around (GAA) transistor architecture.

It also lists successors such as N2P and later variants.

Still, the video argues China’s progress is measurable and repeatable:

• Huawei is said to have narrowed the performance gap to Apple in roughly “one generation” terms without EUV.
• The video frames TSMC’s 2nm advantage as potentially trackable and reducible over time, rather than impossible to match.

Export Controls Backfired (as Framed by the Video)

The video’s central thesis is that export controls aimed to freeze China around ~7nm, but instead pushed firms toward a domestic workaround-driven strategy:

• It claims restrictions increased incentives to replace foreign tools with domestic DUV alternatives.
• It also claims SMIC has begun testing its own DUV lithography capability (initially described as only accessible via ASML).
