China's largest foundry raises alarm with production of basic 7nm SoCs
China very badly wants to be self-sufficient when it comes to manufacturing chipsets. But it has had a problem as the U.S. has tried to prevent this from happening. China's largest foundry, Semiconductor Manufacturing International Corporation (SMIC), could only produce chips using its 14nm process node compared to the 5nm process node being used by leading foundries TSMC and Samsung (and both will be shipping 3nm chips later this year).
Despite U.S. sanctions, SMIC is beginning work on reducing the process node lead that TSMC and Samsung have
This is important because the lower the process node, the higher the number of transistors that can fit inside a chip. And the more transistors inside a chip, the more powerful and energy-efficient the chip is. With 15 billion transistors in Apple's A15 Bionic, you have to wonder how such components can be designed. The answer is a machine manufactured by Dutch firm ASML, the extreme ultraviolet (EUV) lithography machine.
Even without a $150 million EUV machine, like the one in this picture, SMIC is able to work on the 7nm process node - China's largest foundry raises alarm with production of basic 7nm SoCs

The EUV machine etches circuitry designs on a wafer that are a fraction of the thickness of a human hair. The machine has been credited with keeping Moore's Law alive; that is the observation made by Intel co-founder Gordon Moore that the number of transistors in chips would double, at first every year. When Moore revised his "Law" in the 1970s, he changed the time frame to "every other year."
In 2020, an export rule change made by the U.S. Commerce Department blocked foundries around the world from shipping cutting-edge chips to China's Huawei if those foundries manufacture chips using U.S. technology. As a result, Huawei has been forced to use Qualcomm's current Snapdragon chips that are modified to run 4G speeds only thus blocking Huawei from producing 5G capable phones.
The U.S. also has taken steps in the past to prevent SMIC from obtaining EUV machines from ASML to prevent China from producing cutting-edge chips. But when we last looked at SMIC last September, it announced that it was spending billions to build new fabs and planned on going after TSMC in the 28nm segment which is used for Wi-Fi chips and other integrated circuits.

Shanghai Tianshu Intellectual Semiconductor Co. (Tianshu Zhixin) announced Wednesday that it's nearing "mass production and commercial delivery" of Big Island, China's first domestically produced 7nm general-purpose GPU (GPGPU).
Tianshu Zhixin said in January that BI was made using an unidentified 7nm process node and 2.5D chip-on-wafer-on-substrate (CoWoS) packaging. On Wednesday, it confirmed our suspicion that BI was made using TSMC's 7nm FinFET process.
It also shared a little more information about what people can expect from BI when it starts to ship. The image below shows Tianshu Zhixin's performance claims in a variety of floating point formats that it teased during the January announcement:

China's First 7nm GPU Nears Mass Production, Pics Emerge

Tianshu Zhixin claimed that BI offers "nearly twice the performance of mainstream manufacturers' products" at a lower power consumption while also offering a more attractive price-to-performance ratio. (Pricing details weren't revealed, however.)
The company said that its "progress of product development and commercial application is 1-2 years ahead of domestic counterparts." That's an important lead to claim as China pushes companies to reduce their reliance on foreign products.

Chinese semiconductor giant SMIC has reportedly been manufacturing 7-nanometer chips since last year, the best sign yet that China has found a way to develop advanced components despite US efforts to curb the country's homegrown silicon capabilities.…
This is based on findings from American semiconductor analyst firm TechInsights, which recently bought a cryptocurrency-mining ASIC manufactured by SMIC and found that it uses a 7nm process after doing a study of the chip's die. The ASIC is designed by a company called MinerVa, which has been mass producing the chip since July 2021, according to its website.
TechInsights said SMIC's 7nm process appears to be a "close copy" of the one used by Taiwanese foundry giant TSMC. However, the firm said the custom chip was likely a "steppingstone" for SMIC achieving a "true 7nm process" that includes both scaled logic and memory bitcells.
The reason for this is crypto-mining ASICs "likely do not feature the typical bitcell memory that true 7nm technology definition requires," so it's more feasible that the chip is mostly a demonstration of 7nm logic.
"This is the most advanced technology product TechInsights has seen from SMIC so far and may be leading to a true 7nm process that incorporates scaled logic and memory bitcells," TechInsights said.
The development will likely be received as bad news for the US government, which has been trying to slow down China's ability to manufacture advanced chips over national security concerns.
While the 7nm crypto-mining chip is probably meant for consumer or commercial use, the process node will likely end up in military applications in China due to the country's "military-civil fusion" doctrine, where private companies must share their technologies with the nation's military.
China's military technology push was the reason Uncle Sam added SMIC, the Middle Kingdom's largest domestic chipmaker, to the US Treasury Department's entity list in December 2020. This was meant to prevent SMIC from acquiring certain American technologies. The United States put a specific restriction in place for items that would allow SMIC to manufacture chips at 10nm or lower.
Even before that, the US had successfully pressured the Dutch government to block ASML — the only provider of extreme ultraviolet light (EUV) lithography machines used to make chips on leading-edge nodes, such as 7nm — from selling such systems to China.
Despite these efforts, China has apparently managed to create finished products on a 7nm node.

China is moving towards advancing itself in the Hi-tech sector. However, the Taiwan incident proved that from a military perspective, they are still a paper tiger, so they will need Russia for Military Muscle. The two will be drawn together by need more than want. An alliance is already in progress, but China will now be forced to overtly support Russia or risk losing everything, for they are not strong enough to stand up to the US military war machine.
