For 1C, the bit line pitch is ~36 nm, which is hitting that limit. The word line pitches and active area pitches are even smaller.
MMP is above 40 nm, making use of difficult double patterning.

For DRAM, there is no rapid increase in mask count as seen with logic. Instead there are changes such as from direct print to SADP to SAQP, but these are long established processes (for the DRAM/Flash makers). There was a mention of combining some array patterns with peripheral patterns in one...

The number of EUV layers will be reduced by 30% compared to the plan 2~3 years ago
Samsung Electronics, which is making an all-out effort to secure yields, has decided to reduce the number of layers of extreme ultraviolet (EUV) lithography equipment from the...
Pros:
1. Shorter wavelength
2. No tin residue
3. Larger depth of focus at same resolution (lower NA can be used)
Cons:
1. Need Ru/Be mirrors
2. Power output relatively low
3. More electron blur
4. Higher stochastics
The Alpha-Machine is a project aimed at demonstration of a lithography machine based on xenon EUV light source and optics at shorter than 13.5-nm wavelength, being currently developed at Institute for Physics of Microstructures and Institute of Applied Physics of the Russian Academy of Sciences...

Some interesting history from Lip-Bu Tan's previous stay at Intel (from the linked Yahoo article above):
Tan's views were shaped by months of reviewing Intel's manufacturing process after the board in late 2023 appointed him to a special role overseeing it, according to a regulatory filing.

"everything undergoes constant optimization"
I wonder how this could be documented. Intel had strict internal process control and documentation, at least 2 decades ago.
