Durable, heat-resistant multi-layer coatings and coated articles

Abstract

A method of providing a durable protective coating structure which comprises at least three layers, and which is stable at temperatures in excess of 400° C., where the method includes vapor depositing a first layer deposited on a substrate, wherein the first layer is a metal oxide adhesion layer selected from the group consisting of an oxide of a Group IIIA metal element, a Group IVB metal element, a Group VB metal element, and combinations thereof; vapor depositing a second layer upon said first layer, wherein said second layer includes a silicon-containing layer selected from the group consisting of silicon oxide, silicon nitride, and silicon oxynitride; and vapor depositing a third layer upon said second layer, wherein said third layer is a functional organic-comprising layer. Numerous articles useful in electronics, MEMS, nanoimprinting lithography, and biotechnology applications can be fabricated using the method.
