Abstract
A method of selectively depositing a metal on a surface is disclosed. The method comprises selectively coating a surface with a surface active agent, having a first surface energy, to form a coated surface having a coated portion capable of burying a higher surface energy material applied thereto and an uncoated surface pattern not so capable. The selectively coated surface is then treated with a solution, having a second surface energy higher than the first, comprising a species selected from the group comprising (1) a species capable of reducing an activating metal ion to an activating metal and (2) an activating metal species capable of participating in an electroless metal deposition, to form a surface having the species deposited atop the uncoated pattern.
