Abstract:
1. An insulation film for microelectronic materials comprising: an insulating part having a film form comprising a siloxane-modified hyperbranched polyimide having a three-dimensional structure and having a siloxane structure represented by the following structural formula (1) in a molecule thereof; wherein said siloxane-modified hyperbranched polyimide has a dendritic structure and is obtained through imidization of a siloxane-modified hyperbranched polyamic acid obtained by reacting an aromatic tetracarboxylic dianhydride, an aromatic triamine and a siloxane-containing compound represented by the following structural formula (2): wherein R1 represents a hydrocarbon group having from 1 to 6 carbon atoms, and n indicates an integer of from 1 to 50; wherein R1 represents a hydrocarbon group having from 1 to 6 carbon atoms; R2 represents a divalent organic group; X represents an amino group, a carboxylic acid group, a halide carboxylate group or a carboxylic anhydride group; and n indicates an integer of from 1 to 50; wherein said aromatic triamine is at least one of tris(3-aminophenyl)amine, tris(4-aminophenyl)amine, tris(3-aminophenyl)benzene, tris(4-aminophenyl) benzene, 1,3,5-tris(3-aminophenoxy)benzene, 1,3,5-tris(4-aminophenoxy)benzene (TAPOB) and 1,3,5-tris(4-aminophenoxy)triazine; and wherein said siloxane-modified hyperbranched polyimide has reactive end groups thereof in which at least one of the reactive end groups is modified through a reaction with any of fluorine-containing compounds of monovalent amines, monovalent carboxylic acids, monovalent halide carboxylates or monovalent carboxylic anhydrides.
