I think when it says ideal performance, that would indicate they think it can do HVM at 28nm.

Single-Component High-Resolution Dual-Tone EUV Photoresists Based on Precision Self-Immolative Polymers.
University of Science and Technology of China, Department of Polymer Science and Engineering, CHINA
Abstract
Electron beam (EB) and extreme ultraviolet (EUV) lithography are advanced techniques capable of achieving sub-10 nm resolutions, critical for fabricating next-generation nanostructures and semiconductor devices. However, developing EUV photoresists that meet all demands for resolution, line edge roughness (LER), and sensitivity (RLS) remains a significant challenge. Herein, we introduce high-performance photoresists based on single-component self-immolative polymers (SIPs) with inherent signal amplification via cascade degradation. These SIPs function as dual-tone photoresists under both EB and EUV lithography, with performance primarily determined by the exposure dose. Lithographic evaluations show that discrete SIPs provide significant improvements over disperse counterparts, achieving higher resolution and reduced LER. Specifically, a discrete SIP with a DP of 12 produces a line-space pattern with a resolution of approximately 18 nm and an LER of 1.8 nm, compared to 21 nm resolution and 2.5 nm LER for disperse SIPs. Additionally, these SIP-based photoresists, enriched with aromatic structures, exhibit excellent etch resistance. The single-component nature and potential to address the RLS trade-off underscore the promise of discrete SIPs for EUV lithography.
Oriental Crystal Source PanGen DMC completes verification based on rapid process feedback to detect potential bad spots in the layout in advance
With the evolution of technology nodes, the integrated circuit manufacturing process itself has become more and more complex, and it has become increasingly difficult for designers to have a comprehensive and systematic understanding of the process, resulting in the need for repeated iterations of new products during the process end tape-out, which has led to a long period of yield ramping, increasing the cost of production and extending the time it takes for products to be put on the market. According to McKinsey statistics, it currently takes about 12 to 18 months of repeated iterations in the semiconductor industry from tape-out to mass production to improve the yield of new products.
Based on the solid computational lithography platform PanGen® and rich industry practice experience, Oriental Crystal Source has innovatively developed the PanGen DMC® (Design Manufacturability Check) product. Its embedded D2C (Design To Contour) fast lithography feedback engine can package the full set of FAB OPC Recipe solutions in the form of an AI model, allowing users to quickly and accurately estimate the final morphology (Contour) of the Design on the silicon wafer based on the original Design, and thus predict potential risks in the design layout in advance.
Through verification, the prediction error is less than 1nm
The actual test results in a domestic advanced node FAB show that the difference between the predicted results and the actual results of Oriental Crystal Source PanGen DMC® on the full chip scale is less than 1nm in more than 99% of the layout positions, proving that its D2C fast lithography feedback engine can accurately capture the behavior of the entire OPC recipe and provide Contour results that are very close to the complete OPC recipe.
Defect capture rate exceeds 90%
In addition, as process technology becomes increasingly complex, it is difficult to include all aspects of the entire process with abstract rules alone. Therefore, a design layout that passes the rule-based DRC (Design Rule Check) check on the design side does not mean that it can perform well on the process side. PanGen DMC® can estimate the final lithography morphology of the design layout and provide direct feedback to the process side by using FAB lithography sign-off in advance. The actual measurement results in a domestic advanced node FAB show that DMC can predict serious defects in the design before sending it to OPC, with a Capture Ratio of over 90%.
Help improve manufacturability
In fact, DRC checking only tells a black-and-white conclusion of whether there is a violation or not. It is impossible to know how much impact a certain degree of violation will have on the process side. PanGen DMC® can present the impact to users in a very visual way based on the model, helping users to weigh the violation handling according to the situation in practice. Therefore, whether for the manufacturing side or the design side, this product can be used as a very powerful supplement to the existing DRC (Design Rule Check) tool. On the basis of respecting the customer's existing workflow, it helps customers to more comprehensively discover the risks of the layout in process manufacturability in addition to DRC checking, thereby accelerating iterations, reducing time costs, and enabling new chip products to increase yield faster during the tape-out process and be brought to market earlier.
Comprehensive and forward-looking computational lithography platform PanGen ®
So far, Oriental Crystal Source's computational lithography platform PanGen® has formed eight major product matrices, including Model, DRC, SBAR, OPC, LRC, DPT, SMO, and DMC, with a complete computational lithography-related EDA tool chain. In addition, the PanGen® platform not only has OPC optimization functions suitable for mature process nodes, but is also the first mask optimization tool with full-chip reverse lithography (ILT) functions with a CPU+GPU hybrid computing architecture, and has key technologies for application in advanced process nodes. The research and development and verification of PanGen DMC® will further consolidate Oriental Crystal Source's technical integrity and leadership in the field of computational lithography, and bring more comprehensive and forward-looking computational lithography solutions to the industry.

"competitive global"
There is a problem with these kind of statement and a example why these stooges got all wrong from day 1.
Let suppose that a company in China, for example SMEE, comes with a EUV machine capable of patterning 50 300mm Wafers Per Hour, a pretty uncompetitive machine compared to the 150 300mm WPH of ASML, right? BUT there is a catch, ASML cannot sell EUVL machines in China so whatever EUVL machine China develop is already in a competitive footing even is going to be used by SMIC or HHGrace for experimenting with EUVL. Every month or year that ASML is not selling their machines is a chance for this domestic EUVL machine to become the dominant machine in the Chinese market. ASML is competing globally, basically they have a monopoly, but not in China, where they are not allowed to sell. These stooges are seeing this situation from the POV of a stockholder and they are ignoring or even deliberately obfuscating the dynamics that play these kind of situations.
FeedBack Loop: ASML is probably the biggest reason why SMEE lithography machines was in such state. The more a machine breaks, the more a machine has to be serviced and the more workers complains the better the machine gets. It happens in software, it happens in hardware. Is a "feedback loop".
Until a few years ago due US sanctions and the naivete Chinese liberals, SMEE never benefited from the same feedback loop that ASML enjoyed with Chinese FABs and academy. The situation now is that Chinese fabs are more willing to test and use domestic lithography machines, the Chinese government is more willing to push for the use of domestic machines in new fabs and ASML is getting more and more restricted. This has opened a opportunity for domestic companies for the feedback loop needed to become more and more competitive. That if the same liberals don't throw a wrench and prefer China to be stuck using legacy scanners forever.

Beijing vs Shanghai vs Jilin
you know what i m saying, there is stiff competition going among local governments..
in few years we might have multiple choices in domestic DUV/EUV machine..
