Abstract: The present invention relates to a surface treatment composition and a method for treating the surface of a substrate using the same. More particularly, the present invention relates to a surface treatment composition comprising a liquid medium as a main component, which prevents a substrate surface from being contaminated with metal impurities from the surface treatment composition and stably provides an extremely clean substrate surface, and also relates to a method fro treating the surface of a substrate by using the same. The composition comprises water, hydrogen peroxide, an alkaline compo und and 2 , 2-Bis- (hydroxyethyl) - (iminotris) - (hydroxymethyl) methan and/ or nitrilotriacetic acid.
