Abstract:
A method for the nucleation controlled deposition of thin films suitable for use as the dielectric of a capacitor on a substrate member by metal-organic chemical vapor deposition which comprises the steps of:(a) placing the substrate member in a chemical vapor deposition apparatus, the substrate having deposited upon a portion thereof a film of an electrically conductive material;(b) heating the substrate to an elevated temperature in the range of from about 300.degree. C. to 800.degree. C. within the apparatus;(c) introducing vaporized metal-organic precursors carried by an inert gas into the apparatus, and thermally decomposing the precursors to substantially simultaneously yield a first thin film of a homogenous composition upon the electrically conductive material, and a second thin film of a composition different from the first thin film upon the exposed substrate surface.
