Is there a reason EUV labs don't collocate with synchrotron FEL lasers?
- aboardRat4 2y agoYes. Nucleophobia. Same reason it's called "euv" and not "soft x-ray".
- DoctorOetker 2y ago"because the bit flips would then already have infected your processor in the factory" ?
- cyberax 2y agoIndeed, synchrotron sources are considered to be a possible light source for lithography. China is especially interested in them, since they can be done with a homegrown technology: https://www.eenewseurope.com/en/chinas-synchrotron-euv-litho-light-source-is-no-sanctions-buster/ https://www.eenewseurope.com/en/chinas-synchrotron-euv-litho... From what I understand, tin-based sources are easier to work with because they are point-like. All the energy is produced from a tiny droplet. Synchrotron sources produce much wider beams, that need to be re-focused properly.
- SAI_Peregrinus 2y agoSynchrotron FELs are already used, and their construction paid for due to their scientific uses. Building new ones would require new synchrotrons, which are more expensive than the crazy "hit molten tin drops with lasers to make a plasma" scheme the ASML machines use.
