METHOD FOR FORMING THIN FILM, METHOD FOR FORMING MULTILAYER THIN FILM HAVING THE THIN FILM THEREIN, ELECTRONIC DEVICE, AND ORGANIC ELECTROLUMINESCENCE ELEMENT

摘要

Provided is a thin film forming method wherein the physicochemical properties of a thin film composed of an organic material are changed by forming the thin film and then by physicochemically processing the thin film, without changing the chemical structure of the organic material which forms the thin film. In the method, even in the cases of forming the organic thin film and an organic multilayer thin film by employing an application method which enables continuous manufacture, mixing of the lower layer material with the upper layer (contamination) and interface troubles are improved. An organic EL element having a high external extraction quantum efficiency and a long light emitting service life is provided using the method, and the electronic device and the organic EL element which include the organic thin film are also provided.
