In 2006, Intel talked about a non-removable pellicle "as a backup approach to the pellicle-less methods pursued by suppliers and EUVL partners." The paper is here: EUV Pellicle Development for Mask Defect Control. If they're using pellicles now, it would have to be the one from Mitsui (which...
ESOL's position is interesting. I imagine its customers will be EUV mask shops. But complete pellicle testing still requires it to be immersed in the hydrogen plasma of an ASML EUV machine.

They now are doing dual exposures with EUV.
Indeed, it's surprising they don't also apply this to memory; what's not being said tells more.
It's the sparse patterns.

Nvidia (NASDAQ:NVDA) CEO Jensen Huang said Taiwan Semiconductor Manufacturing (NYSE:TSM) will provide the foundry support for the "revolutionary" chips they are making with Intel (NASDAQ:INTC).
"Nvidia and Intel are both successful...
"PSM" may not be an appropriate term for EUV masks anymore, since the light goes through a phase shift dependent on angle and pattern just from the EUV multilayer itself. There has been substantial work on low-n absorbers, but the benefits, again, appear pattern-dependent.
I refer to this paper https://www.spiedigitallibrary.org/conference-proceedings-of-spie/12750/127500N/EUV-pellicle-technology-for-high-volume-wafer-production/10.1117/12.2688127.short where TSMC reported changing EUV pellicle materials 3 times in 2020-2023. But at 400W, the 2023 material was...
Besides being expensive on their own, EUV pellicles limited throughput due to transmission as well as rupturing or destabilizing faster at higher power. So pellicle-less procedures have been developed. DUV pellicles are much cheaper and do not limit throughput this way but still need to deal...
Apparently Comet Lake and some other processors were discontinued as of July 1st this year, so they're just renaming a discontinued product as a bookkeeping formality?

So, should we call this 10th Gen or Core Series 1?
It appears that Intel is experiencing a sense of nostalgia, as the chipmaker (via momomo_us) has introduced the Core i5-110 processor, based on Comet Lake. Comet Lake is a stroll down memory lane for many of...

Mitsui Chemicals licensed technology from ASML and IMEC to produce EUV pellicles which they sell. Samsung and TSMC have published their ongoing evaluation efforts. TSMC has gone so far to set up its own EUV pellicle infrastructure in preparation for producing its own pellicles for its own use...
Very unclear article source: https://www.etnews.com/20250910000245
However, it remains unclear whether Intel will procure glass substrates in-house or through external collaboration. Mass production requires significant investment, and multiple manufacturers are needed to ensure a stable...
