Huawei is reportedly all out of its homegrown chips however a brand new patent may very well be a gamechanger


Again in Could 2019, Huawei was positioned on the U.S. entity record which it nonetheless is on right now. The U.S. cited safety as the rationale why it put the corporate on the record which prevents it from accessing its U.S. provide chain, together with Google. Precisely one 12 months later, the U.S. modified its export guidelines stopping foundries utilizing American expertise to supply chips from sending cutting-edge silicon to Huawei. 

A brand new report says that Huawei has used each single final homegrown Kirin chip

Consequently, Huawei cannot even receive its personal Kirin chips designed by its HiSilicon unit. At one time, Huawei was TSMC’s second-largest buyer after Apple. For its final two flagship collection, the photography-focused (no pun supposed…or was it?) P50 line launched in 2021 and this 12 months’s Mate 50 line (apart from the low-priced Mate 50e), Huawei obtained permission to make use of Qualcomm’s top-of-the-line SoCs designed to not work with 5G.

A brand new report launched by analytical agency Counterpoint Analysis (through the English-language South China Morning Publish) says that based mostly on its computations, Huawei has used up all of its personal homegrown chips. Within the report on smartphone software processor (AP) market share, Counterpoint mentioned, “Based mostly on our checks and sell-through information, Huawei has completed its stock of HiSilicon chipsets.”
Through the third quarter of this 12 months, HiSilicon’s share of the smartphone AP market was zero %. That was down sequentially from the .4% share it had final quarter and the three% share it had through the third quarter final 12 months. The highest designers of AP chips for smartphones embrace MediaTek, Qualcomm, and Apple.

In October, The Monetary Instances reported that Huawei is trying to redesign its telephones to work with much less superior chips produced by Chinese language foundries. China’s largest foundry is SMIC and whereas it was capable of produce chips utilizing its 7nm course of node, these chips had been for cryptocurrency mining and never complicated sufficient to drive a smartphone. SMIC and different Chinese language foundries are producing 14nm chips at greatest, removed from the cutting-edge 3nm chips that TSMC and Samsung Foundry are delivery subsequent 12 months.

Which means whereas Huawei will be capable of provide 5G connectivity on its new telephones if it makes use of silicon made in China, its telephones won’t be as quick because the competitors. That is as a result of the upper the method node, the decrease the transistor rely in these chips. And sporting fewer transistors, the chips will probably be much less highly effective and energy-efficient. The final time the iPhone had a 14nm chipset was when the Samsung model of the A9 chip was utilized in some iPhone 6s and iPhone 6s Plus fashions again in 2015.

Huawei has finished a tremendous job designing its personal HarmonyOS working system (now on its third model) and it changed the Google Cellular Companies ecosystem with its personal Huawei Cellular Companies. However since Huawei will not be capable of discover a foundry capable of produce cutting-edge chips with out utilizing U.S. expertise, the export rule change is Huawei’s largest challenge at this level.

Huawei’s EUV patent may very well be a gamechanger

And the U.S. has additionally labored with the Netherlands to stop the export to China of essential Excessive Ultraviolet Lithography (EUV) machines. Largely made by a Dutch firm known as ASML, these are college bus-sized machines that value $150 million every and are used to etch circuitry patterns thinner than a human hair on silicon wafers. These patterns should be extraordinarily skinny in order that billions of transistors might be positioned inside a chip.

Final month, a senior Dutch official mentioned that the Netherlands must defend its financial pursuits. In different phrases, it’d quickly have to permit ASML to export EUV machines to China as an alternative of passing up on the financial impression of permitting these machines to be shipped to China. As soon as this occurs, we may see Chinese language foundries like SMIC make a push to develop cutting-edge AP chips for smartphones.
However Huawei won’t should depend on ASML. Final month the corporate obtained a patent permitting it to create its personal EUV machine that can be utilized to fabricate chips utilizing a 7nm course of node and decrease. If Huawei could make an EUV machine with out utilizing U.S. patents, it can have a robust shot at bringing again its Kirin chips.
