One aspect of the present invention is a method of processing a substrate. In one embodiment, the method comprises forming an electrical conductor on or in the substrate by providing a mixture comprising metal particles and an electroless deposition solution and electrolessly depositing a metal matrix and co-depositing the metal particles. In another embodiment, the method comprises forming an electrical conductor on or in the substrate by providing a mixture comprising metal particles and an electrochemical plating solution and electrochemically plating a metal matrix and co-depositing the metal particles. Another aspect of the present invention is a mixture for the formation of an electrical conductor on or in a substrate. Another aspect of the present invention is an electronic device.
