This discussion will be limited to those lithography … Web16 Aug 2008 · As a rule of thumb: A resist with a layer thickness of 1.0 µm at 4000 rpm will be 2.0 µm thick at 1000 rpm. At 250 rpm, this resist will have a thickness of 4.0 µm, but with major edge bead formation. By varying the spin speed (250-9000 rpm), the layer thickness of each resist can in general maximally be quadrupled. 30 seconds are sufficient ...
