There are many characteristic features that must be preserved during thin film deposition. Many factors such as temperature, thickness of the film can produce various results. One of the main properties to consider is surface. The surface of the material thin film is deposited to can be smooth or rough. Thin films with high surface roughness can have different electric functions and conductivity. Having tools that deliver precise numbers, one can control and modify film preparation conditions (impurities, rate, etc.) and different growth approaches, which will enable manipulation with surface forms. Modern devices in the industry provide access to important data for thin film roughness control in real-time.
