  • Method of forming a metal trace
    Publication number: 20060258136
    Abstract: Disclosed is a method of forming a metal trace on a substrate. The method includes inkjet printing a chemical ink comprising a metal containing compound on the substrate surface to form an ink drop thereon, and heating the substrate to a suitable elevated temperature. The ink drop undergoes at least one of decomposition and reduction due to the substrate temperature to form a metal on the substrate in a controlled atmosphere.
