COMPOSITION FOR WATER-REPELLENT TREATMENT OF SURFACE, AND METHOD FOR WATER-REPELLENT TREATMENT OF SURFACE OF SEMICONDUCTOR SUBSTRATE USING SAME

摘要

The purpose of the present invention to provide: a composition which can be used for water-repellent treating of the entire surface of a semiconductor substrate having a pattern formed by laminating a Si-containing insulating layer and a metal layer, at one time; and a method for water-repellent treatment of the semiconductor substrate surface using the composition. The present invention relates to: (1) a composition for water-repellent treatment of a semiconductor substrate surface comprising a) at least one kind of a compound selected from the group consisting of a long-chain alkyl tertiary amine and a long-chain alkyl ammonium salt, b) a base or an acid generating agent, having a condensed ring structure or forming a condensed ring structure by generating a base or an acid and c) a polar organic solvent, and (2) a method for water-repellent treatment of the semiconductor substrate surface having the pattern formed by laminating the Si-containing insulating layer and the metal layer, using the composition.
