Abstract:
1. An amorphous film produced by using a radiation-sensitive composition containing 1 to 80% by weight of a solid component and 20 to 99% by weight of a solvent, wherein the solid component has an absorptivity coefficient at a wavelength of 248 nm of 40 L/(cm·g) or more, and wherein the radiation sensitive composition contains a compound B which satisfies the following requirements of: (a) having a structure derived from a polyphenol compound A by introducing an acid-dissociating group to at least one phenolic hydroxyl group of the polyphenol compound A which is synthesized by a condensation between a di- to tetrafunctional aromatic ketone or aromatic aldehyde each having 5 to 36 carbon atoms with a compound having 1 to 3 phenolic hydroxyl groups and 6 to 15 carbon atoms, and (b) having a molecular weight of 400 to 2000, and wherein a total content of the compound B and a solubilizer C is 50 to 99.999% by weight of a total weight of the solid component; wherein the compound B is represented by the following formula 1: wherein each R wherein each R wherein each of R wherein R wherein each of k0, j0, m0, and n0 is an integer of 0 to 3, each of k1, j1, m1, and n1 is an integer of 0 to 3; and each of k2, j2, m2, and n2 is an integer of 0 to 4, satisfying 1≦k0+k1+k2≦5, 1<j0+j1+j2<5, 1<m0+m1+m2<5, 1<n0+n1+n2<5, 1<k1+j1+m1+n1<12, 1<k0+k1<3, 1<j0+j1<3, 1<m0+m1<3, and 1<n0+n1<3.
