Spin Coating: Easy Technique for Thin Films | SpringerLink
3.1 Spin Speed. One of the most significant aspects of spin coating is spin speed. The degree of radial (centrifugal) force imparted to the liquid resin, velocity and the typical turbulence of the air momentarily over it, are affected by the speed applied to the substrate in rpm [36, 63].The ultimate film thickness is mostly determined by the high …

Spin Coating of Photoresists
During coating, the solvent concentration drops and saturates at a value of approx. 15-25 % which depends on the film thickness and is higher for thicker films. The subsequent softbake re-duces the remaining solvent concentration to values of typ. 5 %. A high ambience solvent saturation in the spin coater reduces the attained resist film thick ...
