The substrate is then rotated at high speed (e.g. up to 10.000 rpm) in order to spread the fluid by centrifugal force. A machine used for spin coating is called a spin coater, spin processor or simply spinner. Rotation is continued while the fluid spins off the edges of the substrate, until the desired thickness of the film is achieved.
