2023 sounds really early for EUV but i hope the rumors are true.
Tom Fowey says its a reliable source
If this actually happens in 2023..
But if 2023 is the year of EUV testing then in 2025 China might be ready for sub 7nm nodes.
That would be like having two cherries on top of the made in China 2025 cake.
Probably talking about China Semi account on twitter, previously known as Olala if i'm not mistaken.
A interesting account to follow that will post Chinese published news on twitter.
