| Research Abstract |
We have developed a novel local electrophoresis deposition assisted with a laser trapping technique. Colloidal Au nanoparticle solution is filled in a liquid cell consisting of two conductive substrates. The nano particles trapped by the laser spot are positioned in the vicinity of the substrate, and then they are deposited onto the conductive substrate by controlling electrical potential applied between the two substrates. Fabrications of two-dimensional dot pattern and three-dimensional structures such as pillars have been performed. The deposition parameters such as laser intensity and moving speed of the positioning stage have been optimized to fabricate the pillars.
Furthermore mechanical properties of the micro pillars were evaluated. The mechanical properties of the pillars were evaluated using a micro manipulator put in a sample chamber of a scanning electron microscope. The deflection of the pillars bent with a cantilever of an atomic force microscope was observed.
