  • Seminconductor surface treatment and mixture used therein
    Publication number: 20060025320
    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.
