Abstract

Selectively accelerated or selectively inhibited metal deposition is performed to form metal structures of an electronic device. A desired pattern of an accelerator or of an inhibitor is applied to the substrate; for example, by stamping the substrate with a patterned stamp or spraying a solution using an inkjet printer. In other embodiments, a global layer of accelerator or inhibitor is applied to a substrate and selectively modified in a desired pattern. Thereafter, selective metal deposition is performed.
