<tinybronca[m]><muurkha> "I was guessing that a transitor..." <- how is λ a unit of size??
<oriansj>tinybronca[m]: well if you look at: https://en.wikipedia.org/wiki/Interference_lithography it does say "where λ is the wavelength" and a 5 eV electron has a wavelength of 0.55 nm. one could guess what muurkha possibly ment but it is entirely fair to ask for clarity on what was said in terms you would better understand.
<tinybronca[m]><oriansj> "tinybronca: well if you look at:..." <- Right sorry I didn't know how many things this was used for: https://en.wikipedia.org/wiki/Lambda#Lower-case_letter_%CE%BB
<tinybronca[m]>Confusingly it is wavelength and Channel length modulation parameter

***onebitboi is now known as onebitboy
<oriansj>tinybronca[m]: now which of those two would make the previous seem more reasonable and well thought out. As we need to interpret things written in good faith and clarify to build a shared understanding.
<tinybronca[m]>oriansj: Sorry, what? Are you asking about the different uses of lowercase lambda here?
<muurkha>tinybronca[m]: when we say that something is being fabricated in "a 130nm process" we don't mean that anything in particular in the process is 130 nm across: wires, transistors, anything. what it means, as I understand it, is that the parameter λ = 130 nm
<muurkha>historically wires were 2λ across, and minimal spaces between wires too
<muurkha> https://en.wikipedia.org/wiki/Semiconductor_device_fabrication#Process_node says I'm wrong though
<stikonas[m]>fossy: you merged my PR before I closed all issues...
<stikonas[m]>I haven't tested everyting yet...
<stikonas[m]>I'm travelling a bit but if there are some issues I'll do followon PR once I'm back
