Just like even nuclear power plants are basically glorified steam engines, so is lithography basically glorified analog photography and I find that really weird

Just like even nuclear power plants are basically glorified steam engines, so is lithography basically glorified analog photography and I find that really weird and wonder if maybe there could be another way.
- WJW 4y agoThere is also electron beam lithography which draws the lines one by one instead of illuminating an entire die in one exposure.
- brennanpeterson 4y agoFor a very low density experiment and. A few other cases, it is an option. Or for mask writing. It is very informative to consider the data rate. To approximate (and perhaps do bad phone math) lithography tool has ~1bit per 10nm^2, doing 1 field ever 20s. Or 600mm^2/20s. 30mm^2/s, or about 3E12 bits/s. That's amazing.
