Spin coat 250 thickness rpm
WebSep 26, 2014 · Spin coating is a technique widely used to make polymer films. An excess amount of polymer solution is placed on a substrate, which is then rotated at typically 1000 to 5000 revolutions per minute (rpm) in order to spread the fluid by centrifugal force. Subsequently, the evaporation of the solvent thins the film. The technique is used in the … Webin turn affects film thickness. A warmer system can cause an increase in film thickness. 2.
