Spin coating manipulators are used for depositing metal thin films, polymer coating, organic thin films, and others. An excess amount of the solution is placed by a heated dripper on the substrate. The substrate manipulator is then rotating at high speed. The solvent is usually volatile and evaporates when rotating under a vacuum, leaving a uniform thin film on the substrate. The deposited films have thicknesses ranging from a few nanometers up to hundreds of nanometers.
