Abstract:
A method for forming a multi-component dielectric film for a capacitor comprising:(a) injecting a first source containing a first component into a reaction chamber to be adsorbed on a surface of a substrate; (b) purging residual first source out of the reaction chamber; (c) injecting a mixed gas of Ar and O2 in plasma state into the reaction chamber to react with the first component adsorbed on the substrate; (d) purging by-products and residual gas out of the reaction chamber; (e) injecting a second source containing a second component into the reaction chamber to be adsorbed to the surface of the resulting structure; (f) purging residual second source out of the reaction chamber; (g) injecting a mixed gas of Ar and O2 in plasma state into the reaction chamber to induce oxidation reaction; and (h) purging residual gas and by-products out of the reaction chamber using mixed gas of Ar and O2.
