Huawei's Breakthrough 7nm Chips Projected at 50% Yield: Report

Huawei has ambitious plans to restart the manufacturing of high-end mobile system-on-chips as early as this year, a report by Nikkei claims. The story corroborates an earlier Reuters report that Huawei plans to use SMIC's 7nm-class fabrication technology to make its comeback to smartphone SoCs. But there is a problem that Huawei may reportedly face: high defect density of SMIC's 7nm-class node.

"However, the production yield [quality] for a 7nm node is believed to be quite low, at about 50%, and it still has lots of room for improvement," said Donnie Teng, an analyst with Nomura Securities, in a comment to Nikkei. "The chip being available and the chip being commercially ready are different things. It is still worth monitoring how it goes, but we understand Huawei is willing to invest a lot on this to bring back its chips."

Contemporary mobile SoCs contain tens of billions of transistors and are fairly large. For example, Apple's A16 Bionic comprises of 16 billion of transistors and runs at up to 3.46 GHz. Huawei has historically competed against Apple and Samsung with its flagship smartphones and developed truly advanced SoCs. We do not know what Huawei plans to do at this time, but we are pretty sure that it wants to build something that is competitive enough with high-end smartphones from its rivals.

Meanwhile, the lion's share of SMIC's revenue still comes from chips made on 40nm and older technologies, so the restrictions imposed by the U.S., Japan, and the Netherlands have hardly impacted SMIC financially.

    I could see Huawei redesign the OS to make a crappy 7nm quote-unquote SoC appear to compete with western SoCs. If that's even possible.

    I am surprise they have the capacity for consumer smartphone chips, i would imagine they would be printing chips for higher priority products like telco/base station chips and ai chips.

    Like I said before, sanctions are ineffective in the longer run. While countries can sanction certain technology from going into the hand of another, there is always walkaround to it. For instance, you can just hire the person that have the knowhow. That you can't sanction. China is not some third world country that can't afford to pay if they are in need.
