Can you be more specific about what the difference is?
With photolithography, what most chips are made with, the resist is developed by exposing it to UV light. A mask is used so that the desired parts of the resist are left behind, and the rest is washed away. Contact photolithography places the mask directly against the silicon wafer because it helps the optics during exposure, but the mask doesn't directly remove the resist. In nanoimprint lithograhy, a stamp is press…

If it takes N days of very expensive process to make a mask and the mask can be used M times with cheaper process, what are the thresholds where it is not cost effective?

#13For those who are not aware, and I think it is important to Note, Canon is not a new entry to the industry. They were actually competing with ASML before they gave up in the early 10s. They are aiming at 5nm in 2025 and extend it to 2nm in 2027+. I guess in real world terms you can add at least 1 year to it even in the most optimistic scenario. I dont expect many logic chips will be using it, given the sunk cost invo…
Even RPI5s with the Broadcom BCM2712 which is super high volume is 16nm. If they manage to get 5nm in 2026 at low cost than that's the path to take the SOC crown.
This could even lead to RISC-V SOCs/SBCs at RPI power and price tag (yeah, still dreaming).

#16Canon stock is basically unchanged and is underperforming the SP500 slightly on the 1Y, is the market wrong or is this not going to do anything? One would think disrupting chipmaking would be more reflected in the stock price.

#17While everybody is looking at the SOTA factories, manufacturing is still constrained at the bigger nodes, and bringing the cost down at older processes looks like a worthy goal

How does the stamp not get damaged or degrade over time? Or is this part a consumable / easily replaced?
For the case of chip lithography they'd probably make source masks, copy the first generation a time or two, and use those secondary source masks to produce consumable 'stamps' for production.
Hopefully the stamps maintain sufficient quality across at least a couple batches (50-100+?) of wafers.
