Huawei teardown shows 5-nm laptop chip made in Taiwan, not China
- The Qingyun L540 notebook contains a 5-nm chip made by TSMC in 2020, around the time US sanctions cut off Huawei’s access to the chip maker
- Huawei caused a stir in the US and China last August when it released a smartphone with a 7-nm processor made by Shanghai-based SMIC
Huawei Technologies’ newest laptop runs on a chip made by Taiwan Semiconductor Manufacturing Co (TSMC), a teardown of the device showed, quashing talk of another Chinese technological breakthrough.
The Qingyun L540 notebook contains a 5-nanometre chip made by the Taiwanese company in 2020, around the time US sanctions cut off Huawei’s access to the chip maker, research firm TechInsights found after dismantling the device for Bloomberg News. That counters speculation that Huawei’s mainland Chinese chipmaking partner, Semiconductor Manufacturing International Corp (SMIC), may have achieved a major leap in fabrication technique.
Huawei caused a stir in the US and China last August when it released a smartphone with a 7-nm processor made by Shanghai-based SMIC. A teardown by the Canada-based research outfit for Bloomberg News showed the Mate 60 Pro’s chip was only a few years behind the cutting edge, a feat that US trade curbs were meant to prevent. That revelation spurred celebration across the Chinese tech scene, and a debate in the US about the effectiveness of sanctions.
In the latest teardown, TechInsights discovered a Kirin 9006C processor fabricated via TSMC’s 5-nm method, which was assembled and packaged around the third quarter of 2020. Industry experts had previously speculated that SMIC achieved that milestone by developing workarounds to US sanctions, which would have marked a second technological triumph for the Chinese national champion in the span of months.
Representatives for Huawei and TSMC did not provide comment when reached by Bloomberg News.
The advances encapsulated in the Mate 60 smartphone in 2023 cemented Huawei’s role as the standard-bearer for Chinese efforts to wean itself off Western technologies and create domestic alternatives. Chinese consumers snapped up the smartphone in the final quarter, helping the company regain the symbolically important US$100 billion revenue threshold – eroding Apple’s iPhone dominance along the way.
A foray into 5-nm territory would have represented a big leap for the Shenzhen conglomerate, bringing it closer to the most-advanced processes currently in use, mostly centred around 3-nm nodes. Before TSMC cut off ties with Huawei, it was supplying chips as advanced as 5-nm to the Chinese firm.
