Huawei’s shock Breakthrough in Microchip Printing – Destroys massive US Chip Sanctions Campaign
Huawei has patented ultraviolet light conversion technology to eliminate distortion due to interference when operating at extremely short wavelengths.
This development allows you to use the 10nm process to print microchips on its own. So it can not only circumvent US sanctions, but also challenge the entire industry for the production of these devices.
Huawei advanced cellphones, 5G systems and other advanced technology have been been largely banned and blocked by the US and its ‘allied’ states. Google, YouTube, Microsoft, Apple etc are prohibited from selling their systems to Huawei.
Just last month the US declared a new crackdown, forcing its ‘client states’ to stop all sales of advanced microchips to China.
In this context Huawei’s breakthrough has immense importance in breaking the US embargoes, which are clearly illegal under WTO trade rules.
The EUV lithograph.
Extreme ultraviolet (EUV) lithography is so complex that it took the Dutch company ASML 17 years and more than €6 billion of investment to create a commercial facility for its application. In it, droplets of molten tin are irradiated twice with a laser, first to give them the shape of a pancake, and then to evaporate it.
The result is a microcloud of plasma that emits EUV light with the desired parameters. The process occurs at a frequency of 50,000 times per second.

Mirrors in a lithographic machine
This technology is extremely classified, only five companies worldwide have access to it: Intel and Micron in the US, Samsung and SK Hynix in South Korea, and TSMC in Taiwan.
Other manufacturers, such as Huawei, used to simply order chips from TSMC, but after the imposition of US sanctions, this option was no longer available.
It is extremely difficult to replicate the technology, because the necessary EUV radiation is balanced at the edge of the UV and X-ray spectrum.
However, Huawei engineers managed to find a way out using a mirror system to combat the effects of interference. The original beam is divided into ‘secondary beams’, which are transmitted to microscopic mirrors with individual rotation parameters.
Dutch Foreign Trade Minister Liesje Schreinemacher told the country’s parliament in November that ASML’s chip technology was a jewel in the country’s crown to be protected.
US trade sanctions imposed on China this summer specifically targeted EUV technology imports. According to Bloomberg, Dutch officials have been urged by the US to refuse export licenses to China.
The news that local champion Huawei has found a way to develop the chips itself is likely to raise alarms among Western officials.
Huawei did not respond to a request for comment.
EUV machines cost between $150 and $300 million each and are about the size of a London bus. Factories typically require between 9 and 18 machines, pushing the cost of new chip fabs well into the billions.
ASML’s microchip manufacturing machines are used by the world’s leading chipmakers such as Intel, Samsung and Taiwanese chip giant TSMC. In January 2022, Intel ordered five EUV machines to help equip a new chip fab.
Separately, Huawei said on Friday that it was “back to normal business” after two years of disruption sparked by US sanctions.
The Chinese company has signed more than 20 patent license agreements this year, covering smartphones, connected vehicles, networking and the Internet of Things, according to Alan Fan, the company’s global head of IP.

In a year-end message, Chairman Eric Xu said the company had emerged from “crisis mode,” saying, “US restrictions are now our new normal and we are returning to normal business operations.”
Former US President Donald Trump imposed sanctions on Huawei in 2019, including a ban on using Google’s Android mobile operating system, which Huawei’s consumer smartphone division relied on.
Other western nations followed with similar bans, including an order by then-Prime Minister Boris Johnson to remove Huawei equipment from key UK telecoms infrastructure in 2020.
”The bans were imposed in an attempt to destroy Huawei and maintain US tech dominance, with the initial excuse that it could be forced to work with Beijing and offer backdoor access to security communications systems. Later ubiquitous bans and sanctions on Chinese firms have become a clear trade war..”
Sanctions caused Huawei’s global revenue to fall by a third in 2021, but Mr Xu said Huawei’s 2022 sales are on track to remain at around 636.9 billion yuan (£76.6 billion).

Huawei logra un gran avance en la impresión de microchips y elude las sanciones de EE. UU.
. by elcomunista.net
Huawei ha patentado la tecnología de conversión de luz ultravioleta para eliminar la distorsión debida a la interferencia cuando se opera en longitudes de onda extremadamente cortas.
Este desarrollo le permite utilizar el proceso de 10 nm para imprimir microchips por sí solo. Y así, no solo para eludir las sanciones estadounidenses, sino para desafiar a toda la industria por la producción de estos dispositivos.
La litografía ultravioleta extrema (EUV) es tan compleja que la empresa holandesa ASML necesitó 17 años y más de 6 mil millones de euros de inversión para crear una instalación comercial para su aplicación.
En él, las gotas de estaño fundido se irradian dos veces con un láser, primero para darles la forma de un panqueque y luego para evaporarlo. El resultado es una micronube de plasma que emite luz EUV con los parámetros deseados. El proceso ocurre a una frecuencia de 50.000 veces por segundo.
Espejos en una máquina litográfica
Esta tecnología está extremadamente clasificada, solo cinco empresas en todo el mundo tienen acceso a ella: Intel y Micron en EE. UU., Samsung y SK Hynix en Corea del Sur y TSMC en Taiwán.
Otros fabricantes, como Huawei, solían simplemente pedir chips a TSMC, pero después de la imposición de las sanciones de EE. UU., esta opción dejó de estar disponible. Es extremadamente difícil repetir la tecnología, porque la radiación EUV necesaria se equilibra en el borde del espectro UV y de rayos X.
Sin embargo, los ingenieros de Huawei lograron encontrar una salida utilizando un sistema de espejos para combatir los efectos de las interferencias. El haz original se divide en «haces secundarios», que se transmiten a espejos microscópicos con parámetros de rotación individuales.
Esto permite ajustar los efectos de interferencia para su neutralización mutua y, como resultado, sumar todos los «sub-haces» en un solo haz con las propiedades requeridas para la litografía EUV .
