Patent ID: 8361375

Claim:
A method for producing a forming mold or electroforming mother die comprising: forming a release layer composed of an organic thin film on a mold surface or mother die surface by contacting the mold or mother die with an organic solvent solution comprising: (i) a silane surfactant represented by formula [1] R n —Si—X 4-n [1] wherein: R is selected from the group consisting of an optionally substituted hydrocarbon group having 1 to 20 carbon atoms, an optionally substituted halogenated hydrocarbon group having 1 to 20 carbon atoms, a hydrocarbon group having a linking group which has 1 to 20 carbon atoms, and a halogenated hydrocarbon group having a linking group which has 1 to 20 carbon atoms; X is selected from the group consisting of a hydroxyl group, a halogen atom, an alkoxy group having 1 to 6 carbon atoms, and an acyloxy group; and n represents an integer of 1 to 3, and (ii) a catalyst capable of interacting with the silane surfactant; wherein a moisture content of the organic solvent solution is set or maintained within a range of from 50 ppm to a saturated moisture content of the organic solvent.
