| 摘要 |
The present invention provides a method for manufacturing a water-repellent film, including an adhesion precursor film forming step of forming, on a substrate, an adhesion precursor film mainly of a Si-O bond with hydrogen directly bonded to Si; an irradiating step of irradiating the adhesion precursor film with excitation energy to increase an OH group present on a surface of the adhesion precursor film to thereby change the adhesion precursor film into an adhesion reinforcing film; and an organic film coating step of coating the adhesion reinforcing film with an organic film by using a silane coupling agent, wherein a content of the hydrogen directly bonded to Si in the adhesion precursor film is 1.0 × 10 17 atoms/cm 2 or more in terms of a H 2 molecule. |
