Abstract:
PROBLEM TO BE SOLVED: To provide a poly(o-hydroxyamide), a preparing process thereof, a polybenzooxazole, a preparing process thereof, a dielectric component containing a polybenzooxazole as a dielectric material and a process for forming this dielectric component, in particularly, to obtain such a polymer having the safety at high temperatures and for use in a microchip as makes it possible to form a minute conductor truck in the microchip. SOLUTION: The novel poly(o-hydroxyamide) is expressed by formula (I). The poly(o-hydroxyamide) can be cyclized to give a polybenzooxazole having a good barrier effect on the diffusion of a metal. The poly(o-hydroxyamide) is coated on a semiconductor substrate, then heated to thereby convert possibly into the polybenzooxazole. A diffusion barrier can be distributed substantially between a semiconductor truck and a dielectric material as the result of the good barrier effect on the diffusion of the metal.

Abstract:
PROBLEM TO BE SOLVED: To enable the use of a new starting material that has a small dielectric constant, good high-temperature stability and good chemical stability and enables the preparation of an insulating polymer. SOLUTION: A new bis-o-aminophenol of formula I (wherein M represents a particular group) is provided. The bis-o-aminophenol enables the preparation of a heat-resistant polybenzoxazole. The bis-o-aminophenol is preferably prepared from a corresponding diol, which is first nitrosated. A nitroso compound is then reduced to an amino compound through the hydrogenation using Pd/C and H 2 . COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a novel polymer easily spreadable on an electronic part with a very favorable electron insulating effect after cyclization, sufficient stability to chemicals and elevated temperatures, good adhesiveness and filling properties. SOLUTION: The present invention relates to an dielectric material for aluminum and copper metallizing being stable at elevated temperature. Polybenzoxazole is prepared by reacting bis-o-aminophenol with a dicarboxylic acid or its activated derivative (acid chloride) to give poly-o-hydroxamide followed by heating for dehydration and cyclization. The dielectric material of this polymer composition is very suitable for filling a narrow trench, surprisingly even though it is dehydrated during cyclization, and the filled trench shows no defect, bubble or crack. The polybenzoxazole has a low dielectric constant (≤2.7) and suitable for an electric insulator and further exhibits favorable adhesiveness to all the surfaces participating in microelectron optics.

Abstract:
PROBLEM TO BE SOLVED: To obtain a new starting material for forming an insulating polymer which has a small dielectric constant, high-temperature stability, and chemical stability. SOLUTION: A new bis-o-aminophenol is expressed by formula I (M is a bivalent residue having a specified structure). Heat-resistant polybenzoxazole is formed out of the bis-o-aminophenol. The bis-o-aminophenol is preferably produced by nitrosating a diol which corresponds to the aminophenol to form a nitroso compound, and hydrogenating the nitroso compound with H 2 in the presence of Pd/C, so as to obtain the amino compound by reduction.
