Abstract:
1. A method for forming a coating of a material on selected portions of a substrate having a plurality of cavities formed in selected portions of a surface of the substrate, each cavity having outer, peripheral sidewalls extending outwardly from the cavity floor, comprising: providing a structure having a release agent thereon; contacting a top surface of the substrate with the release agent to transfer portions of the release agent to the top surface of the substrate while bottom portions of the cavities remain spaced from the release agent to produce an intermediate structure with a surface comprising: the release agent disposed on the top surface of the substrate and with the bottom portions of the cavities void of the release agent; exposing the surface of the intermediate structure to the material to blanket coat the material on both the release agent disposed on the top surface of the substrate and the bottom portions of the cavities; exposing the intermediate structure having the coated release agent and the bottom portions to a process to selectively remove the release agent together with the coating material thereon from the top surface of the substrate while leaving the coating material on the bottom portions of the cavities.
