How is CXMT planning to deal with the unavailability of EUV? It has stretched DUV quite far, but wouldn't that be a bottleneck soon enough?
Looks like it doesn't. They are using multi patterning techniques and self assembly.

Stacked DRAM Solution: Multilayer Horizontal Cell (MHC) 1T1C DRAM​

Abstract:​

Stacked dynamic random access memory (DRAM) technology has garnered considerable attention as a means to continue the relentless pursuit of scaling. In this context, we have developed a five-layer horizontal cell with vertical word line (WL) and pillar capacitor to realize a stacked DRAM architecture. This design boasts an excellent combination of high on-state and off-state current ratio ( Ion / Ioff) of ~1E8, a steep subthreshold slope (SS) of ~93 mV/dec and a moderate threshold voltage ( Vt) of 0.76 V. A novel process integration scheme incorporating boron silicate glass (BSG)/phosphorus silicate glass (PSG) capping doping, double gate formation, channel thickness optimization, and device electrical engineering considerations are presented and discussed. Moreover, we have also explored the feasibility of fabricating a 64-layer structure through the development of critical unit processes. This study suggests a promising approach using multilayer horizontal cells (MHCs) to further advance the scaling of DRAM technology.​

As I said before, the biggest issue with the Chinese government plans to increase the percentage of domestic products used was that the mental barrier against domestication was just too high. The government changed tactics into 70% of state procured chips be make domestically, hopefully with domestically equipement, materials and software.

That is what Stooges think tankers didn't understood when they pushed for exports controls, these controls broke through that mental barrier like anything that the government couldn't. The total of the IT, AI, Electronics and Chip industry are becoming less and less disjointed with time.

You could put Norinco or a Chinese military university in the export control list and get away with it. But pushing Huawei into making chips and SMIC and YMTC to use domestic equipment was stooges strategic mistake.
Yin Zhiyao stated that domestic customers face a mental barrier when adopting domestically produced equipment: actual data shows that leading foreign equipment rarely encounters problems once it's installed on the production line. However, domestically produced equipment often presents numerous issues initially, requiring significant time to resolve. This stems from a preconceived notion that foreign equipment is superior, while domestic equipment is riddled with problems.

Yin Zhiyao shared his 20 years of experience working in the United States, saying, "In fact, when a new piece of equipment from overseas manufacturers enters the most advanced production lines of customers like TSMC and Samsung, its initial performance is not perfect. It takes two or three years, with the help of leading companies like TSMC and Samsung, to gradually debug and improve the equipment, and customers also provide a lot of feedback. When this equipment is introduced to China, it has already undergone two or three years of testing, so domestic customers will definitely receive it in good condition. Domestically produced equipment will also have problems when it first enters domestic production lines. It's not that domestically produced equipment is really bad; it's just that the environment is different. So I hope that domestic customers can give domestic equipment companies more opportunities."​

China's AMOLED display driver chip market is booming: Domestic manufacturers are accelerating their breakthrough, reshaping the global competitive landscape.​


The global display industry is undergoing a significant transformation as production capacity shifts increasingly toward mainland China. From 2020 to 2024, China's share of global display panel manufacturing surged from 50% to 70%, with projections indicating it will reach 80% by 2029. This industrial relocation has created an unprecedented growth opportunity for the domestic AMOLED display driver chip market, which is now experiencing rapid expansion alongside smartphones, wearables, and automotive displays. While global sales of these chips grew at a CAGR of 15.6% over the last four years, the Chinese mainland market outpaced this average with a CAGR of 27.6%, driving China's market share from roughly one-quarter to nearly 40% in just four years.

Amidst this expansion, domestic manufacturers are accelerating their efforts to compete on the global stage, led notably by Yunyinggu. As the world's third-largest independent AMOLED supplier and currently the largest for smartphone brands in mainland China, Yunyinggu has achieved significant milestones, including over 50 million units sold in 2024 alone. It employs a fabless business model that integrates hardware design with advanced software algorithms and pixel compensation circuits. Other key players are also making breakthroughs: OmniVision is mass-producing OLED chips for top-tier panels; Chipone Technology recently launched high-resolution 1.5K TDDI chips utilizing proprietary RRAM storage technology; and companies like Tiandeyu, Galaxycore, and New Image Microelectronics are optimizing algorithms for motion blur, entering the wearable market, or diversifying into automotive and AR applications to meet evolving technical demands.

Looking ahead, the competitive landscape of AMOLED display driver chips is being fundamentally reshaped by China's rise. Although Korean and Taiwanese competitors still hold advantages in scale and first-mover status, Chinese firms are narrowing the gap through rapid technological accumulation, localized R&D teams, and supply chain integration. As demand expands into larger screens with complex temperature requirements, Chinese manufacturers are poised to capture a dominant share of this high-value segment. By 2029, mainland China is expected to account for over half of the global AMOLED driver chip market revenue, solidifying its position not just as the manufacturing hub, but as a critical engine driving innovation and growth in the global semiconductor industry.

during CCTV interview. Yin Zhiyao said,

China's semiconductor equipment industry has achieved a breakthrough from zero to a complete system today. Mature processes are basically self-sufficient, core equipment has entered the world's first tier , and the gap with the international community is continuously narrowing in areas where it has been lacking.

We now have the capability to manufacture the most advanced equipment.

in December 2023, AMEC decided to enter the large flat panel etching equipment field (previously, it relied entirely on imports for approximately 17 types of process equipment). This equipment weighs 150 tons, is 15 meters long and 15 meters wide, and is about two and a half stories high .

When China first commercial EUV machine comes out, probably sooner than most people expect, I think it wouldn't be the best litho machine, probably lower productivity than ASML, mostly good enough for 7nm and not as precise but as long ASML don't sell theirs in China it will be the best EUV lithography machine that Chinese companies can buy and a positive feedback loop around the machine will happen at the absent of ASML that will speed up the development of these machine

How is CXMT planning to deal with the unavailability of EUV? It has stretched DUV quite far, but wouldn't that be a bottleneck soon enough?
so far top 3 giants Samsung , Sk Hynix and Micron hesitant to adapt EUV coz of astronomical cost involved in EUV though this could solve the multi patterning issue but memory manufacturers are still prioritizing older and cheaper methods.

Samsung and SK Hynix are focused on developing 3D DRAM and shrinking architectures rather than just shrinking the old 2D designs with EUV.

this is good for CXMT as their competitors still using old but reliable DUVi machines.
