Abstract: A method for a photon induced conductive material deposition on a substrate is provided. The method includes steps as follows: preparing a first solution comprising metalate, metal ions, or combinations thereof; preparing a first suspension comprising nanoparticles, a light sensitive reducing agent, an electron providing solvent, or combinations thereof; mixing the first solution and the first suspension to form a first reagent on a first substrate; and emitting a light beam provided by a light source and focusing the same onto the first reagent kept on a first region of the first substrate, so as to form a mechanically rigid conductive deposition in contact with the first substrate in a focus point of the light source, wherein the first substrate has a second region exposed to surrounding gas or an air environment.

Abstract: An apparatus includes an optical writing module and an optical characterization module. The optical writing module is configured to emit a laser beam and guide the laser beam toward a substrate. The optical characterization module is optically coupled with the optical writing module such that the optical writing module and the optical characterization module share the same optical path. The optical writing module is configured to emitting an observation light beam toward the substrate. The optical characterization module is further configured to determine whether a mixture of solution and suspension is in contact with the substrate. When the mixture is determined in contact with the substrate, the laser beam is enabled to irradiate the mixture near a surface of the substrate, so as to form a mechanically rigid material deposition in contact with the substrate.
