Abstract: Embodiments of the present invention provide a method of processing a surface of a polysilicon and a method of processing a surface of a substrate assembly. The method of processing a surface of a polysilicon includes forming a material film on the surface of the polysilicon; and processing, by using a chemico-mechanical polishing technology, the surface of the polysilicon on which the material film is formed. The material film is selected such that the polysilicon is preferentially removed in a polishing process.
