The thickest coating using a normal spin cycle is probably 10-15µm. However, reducing the spin-off time to a few seconds at 2000rpm has successfully been used to increase the coating thickness beyond 20µm on a Gamma coater. The substrate is rested for 1min before softbake in order to reduce the edge bead height. | |||
