Recently, it was reported that wafer factories in Chinese mainland are cooperating with a mobile phone giant to use DUV deep ultraviolet technology to try to manufacture 5nmChipsand is expected to be launched soon. Although these rumors are still unconfirmed, according to the opinions of professionals and Mr. Lim's statement, the rumors are not unfounded. ImmersionLithography machineIt is possible to manufacture 5nmChipsAlthough the cost is higher and requires 4 times**, this does not prevent it from achieving the more advanced 2nmChipsFabricate. In Mr. Hayashi's view, immersion DUVLithographyEven hexa-lithography can be performed for more advanced processes. However, the use of DUV technology in advanced processes requires more skill, which can lead to lower yields, lower manufacturing efficiency, and higher costs. Therefore, in there isEUV lithography machineIf available, 7nm is producedChipsEUV is usedViolet lightline, more cost-effective than DUV, saves the time of multiple lanes, and reduces costs. Still, we know that we can't buy it domesticallyEUV lithography machine, so no matter how difficult and costly, only DUV can be usedLithographyto make something more advanced than 7nmChips, which is an unavoidable fact. As a result, it is reported that 5nm is made using DUV technologyChipsNot an exaggeration, very likely. And, if one day 3nm is successfully manufactured using DUV technologyChips, which is also a possible breakthrough. Despite 5nmChipsIt hasn't been launched yet, but as long as it is successful, the US blockade policy will basically fail.
Secondly, let's look at the global sub-5nm processChipsThe current state of the market. At the moment, onlyApplesA17 seriesChips, M3 seriesChips, as wellQualcommand MediaTek's latest SoC uses a sub-5nm process. And apart from theseChipsand everything elseChipsAll use 5nm or more mature processes, 5nm and more mature processesChipsIt occupies more than 97% of the market share. Therefore, as long as the 5nm process can be successfully manufacturedChips, which means at least 97% of the world'sChipsare able to manufacture, only less than 3%.ChipsIt can't be manufactured. In such a market structure, do we still need to worry about lockdowns and suppression?So if this 5nmChipsIt is expected that the US lockdown policy will henceforth become a joke and no longer exist. This also means:Chinese chipsThe industry has officially begun to take off. It's an exciting prospect, what do you think?
duvLithographyIt is currently the most commonly usedSemiconductorsOne of the manufacturing processes, especially suitable for the manufacture of larger sizesChips。However, withSemiconductorsWith the continuous progress of the process, the limitations of DUV technology are gradually exposed. withChipsWith the continuous refinement of the manufacturing process, DUV technology is making more advanced and smaller sizesChipsencountered challenges. For processes of 5nm and below, DUV technology requires more lithography steps and the highest number of times to achieve, which not only reduces manufacturing efficiency, but also may affectChipsyield and cost. Be that as it may, duvLithographyIt is still the most viable option at this time, especially for domestic onesChipsManufacturer-speaking. Since it is not possible to buyEUV lithography machine, Chinese mainland fabs can only rely on DUV technology to manufacture 5nm and below processesChips。Although it is difficult to manufacture and the cost is high, as long as there is enough technology accumulation and investmentChinese chipsThe industry still has the capacity to achieve this goal.
In the future, with the development and innovation of technology, DUVLithographyMore advanced ones are also expected to be availableSolution。For example, infiltrating DUVLithographyBy immersing the lithography solution into the lithography mold, the lithography can be improved to a certain extentResolutionto achieve a higher level of process. At present, this technology has been able to achieve 4-plex immersion lithography mode, but it is expected to be further improved to 6-plex mode or even higher in the future. This will be:SemiconductorsFurther improvements in the process provide more reliable and cost-effective resultsSolution
Except for DUVLithographyThere are other process technologies that are also evolving. For example, the independent innovation technology developed by domestic enterprises - e-beam ** technology, can be passedElectron beamIrradiation comes**Chips, with the traditionalLithographycomparatively, with a higherResolutionand faster speeds. This is related to:LithographyCompared to the ** way, it can better adapt to the fine size and highly integratedChipsManufacturing needs. In addition, there is utilizationNanoSelf-assembly technology preparationChipsresearch and the application of new non-silicon-based materials, etcChipsResearch hotspots in the field of manufacturing processes.
To sum up, DUVLithographyAlthough there are some challenges, it is still currently manufacturing 5nmChipsOne of the most viable options. Through technological innovation and efforts, we have reason to believeChinese chipsThe industry will be able to continue to break through the dilemma and achieve a higher level of process manufacturing.
5nmChipsThe manufacturing success of the pairChinese chipsWhat does it mean in terms of industry?First of all, this means:Chinese chipsThe industry has made important breakthroughs in terms of technological strength and innovation capabilities. Over the years, China has been working hard to narrow the gap with the international advanced level, and this initiative will beChinese chipsThe industry adds new impetus and confidence.
Secondly, 5nmChipsThe manufacturing success will beChinese chipsThe industry brings great business opportunities. Currently, globalChipsThe market is more advanced for a higher levelChipsThe demand is growing. And China is the world's largestSemiconductorsMarkets, localChipsThe vigorous development of the industry will provide strong support to meet the needs of the domestic market and the export market. In addition,ChipsTechnological breakthroughs will drive the development of the entire industrial chain, including equipment manufacturing, materials and other links, to further promote ChinaSemiconductorsUpgrading and development of the industry.
Finally, for the state,ChipsThe take-off of the industry also means that it has enhanced its ability to innovate independently. Against the backdrop of intensifying friction in international relations and **,ChipsIt is the foundation and core of many key industries, masteredChipsManufacturing technology is essential for the development and stability of the country. By inChipsBy strengthening its independent innovation capabilities and technological reserves in the take-off of the industry, China will be able to better respond to changes and challenges in the international situation and protect the country's core interests and security.
In summary, 5nmChipsThe manufacture ofChinese chipsIt is of great significance and significance to the industry. It doesn't just markChinese chipsThe industry's major breakthroughs in technology, business and technology have also brought people confidence and expectations for the future. withChinese chipsWith the take-off of the industry, we have reason to believe that China will become a global oneChipsA key player and leader in the industry.
5nmChipsof the manufacturing pairChinese chipsThe industry is of great significance. Although this news has not been confirmed definitively, it is not unfounded through the analysis of DUV technology and Hayashi Benjian's statement. Although duvLithographyin manufacturing at 5nm and belowChipsWhen facing some challenges, but in the shortfallEUV lithography machineThis is currently the most viable option. Manufactured successfully 5nmChipswill beChinese chipsThe industry brings great business opportunities and enhances China's position in terms of technological strength, commercial competitiveness and supremacy. Therefore, although 5nm has not yet been madeChips, but once successful, it will meanChinese chipsThe industry is officially taking off, and the US lockdown policy will lose its raison d'être. It should be noted that these views are still not supported by conclusive evidence, pending further confirmation.
