Method for manufacturing an electrically conductive metal trace and corresponding metal trace, particularly suitable for transient electronic devices
It is disclosed a method for manufacturing an electrically conductive metal trace (1) comprising depositing metal micro or nano particles (2) in or on a substrate (3); removing an oxide layer (4) around the particles; sintering the particles after oxide layer removal to form the electrically conductive metal trace (1). The method is characterized in that the step of removing the oxide layer is an electrochemical process wherein the metal micro or nano particles are contacted by a reducing agent (5), and the step of sintering is heat sintering induced by light (6). The method is particularly suitable for manufacturing a transient electrically conductive metal trace.
