Process for forming a patterned thin film structure on a substrate
First Claim
1. A process for forming a thin film structure on a substrate, comprising:
- a) printing a negative image of the thin film structure on the substrate using a strippable material consisting essentially of a binder and a re-dispersible particulate having a hydrophilic surface and an interior pore volume in the range of about 0.3 to about 3.0 ml/g, such that the strippable material is present in areas on the substrate where the thin film structure is not to be formed and the strippable material is substantially not present in areas on the substrate where the thin film structure is to be formed;
b) depositing a thin film material on the substrate; and
c) stripping the strippable material from the substrate;
whereby the strippable material and any thin film material formed thereon are removed by said stripping leaving behind the thin film structure.

Abstract
A process for forming a patterned thin film structure on a substrate is disclosed. A pattern is printed with a material, such as a masking coating or an ink, on the substrate, the pattern being such that, in one embodiment, the desired thin film structures will be formed in the areas where the printed material is not present, i.e., a negative image of thin film structure to be formed is printed. In another embodiment, the pattern is printed with a material that is difficult to strip from the substrate, and the desired thin film structures will be formed in the areas where the printed material is present, i.e., a positive image of the thin film structure is printed. The thin film material is deposited on the patterned substrate, and the undesired area is stripped, leaving behind the patterned thin film structures.
