COATING OF NANO-SCALED CAVITIES
Methods, systems, and apparatus for coating the internal surface of nano-scale cavities on a substrate are contemplated. A first fluid of high wettability is applied to the nano-scale cavity, filling the cavity. A second fluid carrying a conductor or a catalyst is applied over the opening of the nano-scale cavity.
