FUNCTION-TRANSFERRING OBJECT, METHOD FOR TRANSFERRING FUNCTIONAL LAYER, PACKAGE AND FUNCTION-TRANSFERRING FILM ROLL

摘要

A function-transferring object (14) is equipped with a carrier (10) that has a rugged nanostructure (11) and a functional layer (12) provided on the rugged structure (11). The functional layer (12) is transferred to an object to be processed (20) by first providing the functional layer (12) on the surface of the rugged structure (11), bringing the functional layer (12) into direct contact with one main surface of the object being processed (20), and subsequently removing the carrier (10) from the functional layer (12). The mean pitch of the rugged structure (11) is 1 nm to 1500 nm, the functional layer (12) comprises a resin, and the ratio (Ra/lor) of the surface roughness (Ra) of the exposed surface of the functional layer (12) to the distance (lor) between the top of the protrusions of the rugged structure (11) and the exposed surface of the functional layer is 1.2 or less. Moreover, the functional layer (12) is disposed inside the recesses (11a) and the exposed surface is in a non-liquid state at a temperature of 20°C when shielded from light. With the invention, it is possible to confer function on the object being processed (20) with high precision.
