Abstract (en)
[origin: WO2021146061A1] Methods of processing substrates are described herein that include depositing a conductive material on a substrate, applying a primer material soluble in water or aqueous acid onto the conductive material, inkjet printing an acid-resistant patterning material reactive with the primer material onto the primer material according to a pattern to form an acid-resistant mask, and exposing the substrate to an acid to etch exposed portions of the conductive material.
