I think ASML DUVi is now banned in China

Regarding Optic Valley conference and the pic of SSA800i scanner, it was expressly labeled for 28nm, not 14/16nm.

Of course DUVi is needed also for 28nm, but for 14/16 you need a better machine, with stricter overlay tolerances. As of today I have read no info on SMEE to be at 14/16nm.
Chinese equipment makers normally use 28nm as a way to avoid attention, so probably they could go as low a 14nm or less. Overlay is not a function exclusive of the scanner, metrology plays a big role. The alignment is exclusive of the scanner but overlay looks like is a process in optical lithography, long story short is interesting that SMEE listed the Diffraction Based Overlay tool for 7nm, why not 28nm? That for me is that they are saying an discrete way that their scanners can produce chips in that process node, 7nm.

The only fab using fully indigenous tools that we know of is the Yandong Microelectronics (YDME) production line in Beijing.

And it isn't even in production yet. That Chinese government report on progress which went out recently also mentioned a 65nm dry lithography tool being available. Yet it said nothing about 28nm or immersion litho tools.

keep in mind that this is not the first phase. The first phase was for 65-90nm process
By April 2023, YDME's Phase I 12-inch wafer line began trial production, with power SBD devices meeting yield targets and a year-end capacity goal of 10,000 wpm.

On November 15, 2024, YDME and its partners injected CNY19.99 billion into Beidian Integration to support its expansion.

YDME plans to deepen its focus on SiPh chips by increasing investments, expanding applications, and scaling operations. The successful fundraising is expected to boost profitability and sustain long-term growth, according to East Money.
so this one has been in production for over a year now.

They seem to be moving to 28-55nm node now. This is a great sign since they will likely be using SMEE DUVi once that line is up and running.

Thank you for putting my Press Release on the Forum

Good report. So according to latest annual report AMEC would be the number ten i guess? or there is a reason why is not in the list?

AMEC:
Full-year revenue is expected to maintain a high growth rate, and R&D efforts will be significantly increased. The company expects to achieve revenue of 9.065 billion yuan in 2024 (1.24 billion USD), a year-on-year increase of approximately 44.73%; of which etching equipment will achieve revenue of approximately 7.276 billion yuan, a year-on-year increase of approximately 54.71%; MOCVD will achieve revenue of 379 million yuan, a year-on-year decrease of approximately 18.11%; LPCVD thin film equipment will achieve its first sales in 2024, with annual revenue of approximately 156 million yuan.
