The superhydrophobic properties are the result of aluminum oxide clusters made on such surfaces.
Abstract: The purpose of the present invention is to grasp the state in which hydrophilic groups of an electrolyte are distributed in a reaction layer for fuel cells. Nitric acid groups are bonded to hydrophilic groups (sulfonic acid groups) contained in a reaction layer for fuel cells, and metal ions capable of forming a nitrosyl complex with the nitric acid groups, e.g., ruthenium ions, are introduced into the reaction layer to dye the nitric acid groups bonded to the hydrophilic groups contained in the reaction layer. When the hydrophilic groups have agglomerated, the nitric acid groups bonded thereto also agglomerate. When said nitric acid groups are dyed with ruthenium, the ruthenium also agglomerates to make it possible to examine said nitric acid groups with an electron microscope.

Abstract: A method for electrofilling large, high aspect ratio recessed features with copper without depositing substantial amounts of copper in the field region is provided. The method allows completely filling recessed features having aspect ratios of at least about 5:1 such as at least about 10:1, and widths of at least about 1 ?m in a substantially void-free manner without depositing more than 5% of copper in the field region (relative to the thickness deposited in the recessed feature). The method involves contacting the substrate having one or more large, high aspect ratio recessed features (such as a TSVs) with an electrolyte comprising copper ions and an organic dual state inhibitor (DSI) configured for inhibiting copper deposition in the field region, and electrodepositing copper under potential-controlled conditions, where the potential is controlled not exceed the critical potential of the DSI.
Abstract: A surface of an object to be plated is subjected to a treatment for palladium catalyst impartation to impart a palladium catalyst to the surface of an insulating part thereof. A palladium conductor layer is formed on the insulating part from a solution for palladium conductor layer formation which contains a palladium compound, an amine compound, and a reducing agent. On the palladium conductor layer is then directly formed a copper deposit by electroplating. Thus, the work is converted to a conductor with the solution for palladium conductor layer formation, which is neutral, without using an electroless copper plating solution which is highly alkaline. Consequently, the polyimide is prevented from being attacked and no adverse influence is exerted on adhesion. By adding an azole compound to the solution for palladium conductor layer formation, a palladium conductor layer is prevented from depositing on copper.

Abstract: Multi-layer microscale or mesoscale structures are fabricated with adhered layers (e.g. layers that are bonded together upon deposition of successive layers to previous layers) and are then subjected to a heat treatment operation that enhances the interlayer adhesion significantly. The heat treatment operation is believed to result in diffusion of material across the layer boundaries and associated enhancement in adhesion (i.e. diffusion bonding). Interlayer adhesion and maybe intra-layer cohesion may be enhanced by heat treating in the presence of a reducing atmosphere that may help remove weaker oxides from surfaces or even from internal portions of layers.
