Spin- coating: Spin-coating is the most common method used when coating a substrate with photoresist. It is a method that presents a high potential for throughput and homogeneity. The principle of spin-coating is that typically a few millilitres of photoresist are dispensed on a substrate which is spinning at several 1000 rpm (typically 4000 rpm).
