Important notes 05.03.2021
- UV doses in the tables are too large. Look at comments in Matias Busek's protocol
- The programmable hotplate is not reliable
- Two times in a row the same procedure for 25 um thick substrate with VWR and programmable hot plates gave good results for VWR hotplate but overdevelopment for programmable hotplate.
- I have observed that the programmable hotplate seems to spend too long time at each step.
