Huawei plans to make 3nm chips, however when?

Huawei Applied sciences, a Shenzhen-based telecommunication tools maker, is reportedly planning to make 3 nanometer chips with deep ultraviolet (DUV) lithography machines regardless of low yields and excessive prices.

An article revealed by Tom’s {Hardware}, an American know-how web site, reported Tuesday that Huawei and Semiconductor Manufacturing Worldwide Corp (SMIC) collectively plan to supply 3nm chips through the use of patented self-aligned quadruple patterning (SAQP) lithography strategies. The article mentioned that 7nm-class course of know-how options 36 to 38nm steel pitches whereas 5nm-class nodes have steel pitches of 30 to 32nm. It mentioned steel pitches for 3nm chips will likely be about 21 to 24nm. 

Steel pitch is the metric to measure the minimal distance between two horizontal interconnects. In 2019, Intel tried to supply a 10nm chip, which had steel pitches of 36nm. However the challenge failed attributable to low yields. 

The Tom’s {Hardware} article mentioned the price of 5nm or 3nm chip manufacturing will likely be excessive, making it not possible for business gadgets. It mentioned the chips can be utilized in supercomputers or navy tools. 

The article was broadly cited by Taiwanese media on Wednesday. 

In March this yr, media experiences mentioned Naura Expertise Group, a Shenzhen-listed agency, began researching SAQP. They mentioned SiCarrier, a Shenzhen-based state-owned-enterprise that works with Huawei, in late 2023 had been granted a patent that entails SAQP. 

SiCarrier filed patents for the SAQP know-how in September 2021 when Naura was additionally concerned on this challenge. 

The SAQP method known as a brute-force technique because it entails pitch-splitting, or the division of a sample into two or three components. The SAQP might be achieved by making use of self-aligned double patterning (SADP) twice.  

It’s unclear when and whether or not Huawei and SMIC can mass-produce 3nm chips. Some know-how columnists mentioned it could take a number of years for them to attain this purpose. They added that, by the point the 2 corporations succeed, the worldwide markets will likely be utilizing 1.4nm chips.  

5nm processors

On February 6, the Monetary Occasions reported that SMIC has put collectively new semiconductor manufacturing strains in Shanghai to make next-generation smartphone processors as early as this yr. It mentioned the corporate will make 5nm Kirin chips with current inventory of US and Dutch-made tools. This report was cited by Taiwan’s DigiTimes. 

In March, some Taiwanese media mentioned SMIC has arrange a analysis group to push for the manufacturing of 3nm chips. However the experiences haven’t but been confirmed. 

As of now, probably the most superior Chinese language processors are 7nm chips made by SMIC in Shanghai. 

In April, Huawei launched its Pura 70 smartphone, which is powered by the corporate’s Kirin 9010 utility processor. 

TechInsights discovered that Kirin 9010 was made with the so-called N+2 course of, the identical method the Kirin 9000s was produced. Final August, Huawei unveiled Kirin 9000s in its Mate60 Professional telephone.

An IT columnist utilizing the pen title RexAA mentioned in an article that Kirin 9010 performs barely higher than Kirin 9000s. Citing the Geekbench benchmark checks, he mentioned Kirin 9010 achieved 4,471 multi-core scores, in contrast with Kirin 9000s’ 4,206 scores. 

He mentioned Kirin 9010’s efficiency is in between that of iPhone 12’s A14 chip and iPhone 13’s A15 chip, which achieved 4,152 and 4,498 multi-core scores, respectively. He mentioned it has been a terrific achievement that the corporate can nonetheless make its personal 7nm chips after being sanctioned by the US for 4 years.  

Nonetheless, the US Semiconductor Trade Affiliation (SIA) mentioned the hole between the US and China when it comes to superior chip manufacturing will proceed to widen. 

The SIA mentioned in a report earlier this month that the US is projected to supply 28% of the world’s most superior processors (smaller than 10nm nodes) whereas China will likely be making solely 2%. It mentioned Taiwan’s share within the superior chip markets will fall to 47% in 2032 from 69% in 2022. 

It mentioned its examine primarily centered on the affect of the US’ CHIP Act funding and China’s efforts to attain processor independence.
