Abstract: A film patterning method is provided. The method comprises: performing a dry etching process on a film to be patterned, so as to form a patterned film; removing a suspended particle on the patterned film; and performing another dry etching process on the patterned film after the suspended particle is removed, to form a final pattern of the film. By moving or completely removing the suspended particle on the patterned film and then performing another dry etching process on the patterned film to etch away the etching residue, existence of the etching residue is completely avoided in the final pattern of the film, so that the product yield is improved and the product quality is ensured.
