Why would I choose a soda lime substrate for my photomask?
It’s cheap and readily available and works great in the VIS range.
Why would I choose a quartz substrate for my photomask?
Quartz has better UV optical properties and a lower TCE (Thermal coefficient of expansion), but it's also expensive.
What kind of software would you suggest to design photomasks?
Klayout - klayout.de (It’s free) A good layout tool but not a great editor but lots of strong features under the hood. On the higher [...]
