Claim Text:
1. A method of fabricating a flexible imprint mold, comprising: (a) preparing a polymer elastic support, which has a thickness from 0.1 mm to 3 mm and a tensile modulus from 1 to 15 N/mm (b) forming a film of a silicon containing photo-curable material on a mold master; (c) placing the polymer elastic support onto the mold master; (d) using a UV radiation to cure the silicon containing photo-curable material in a nitrogen atmosphere to form a rigid patterning feature layer, which has a tensile modulus of more than 20 N/mm (e) removing the polymer elastic support and the rigid patterning feature layer from the mold master; and (f) oxidizing a near-surface region of the rigid patterning feature layer into silica.
