Abstract:
A photolithographic pattern-forming material as a multilayered integral body which comprises:(a) a substrate; (b) a photosensitive layer formed on one surface of the substrate (a), said photosensitive layer formed from a chemical-amplification photoresist composition; and (c) a composite layer for generation of a near-field light, which is formed on the photosensitive layer (b), consisting of (c1) a first dielectric layer of a dielectric material, said layer having a thickness not exceeding 150 nm, in direct contact with the photosensitive layer (b), (c2) an intermediate layer of a non-linear optical material formed on the first dielectric layer (c1), and (c3) a second dielectric layer of a dielectric material formed on the intermediate layer (c2), the layer (c2) being sandwiched between the first dielectric layer (c1) and the second dielectric layer (c3).
