Thickness vs time spin coating

Web24 Oct 2016 · Spin Coating is basically a procedure which is used to deposit uniform thin films to any flat surface of work piece. Usually a small amount of coating material is applied on the centre of the work piece’s surface when the disk is spinning at very low speed. Here in this process we are using the basic principle of centrifugal force.
