A method of forming mono-disperse iron-oxide core metal shell nanoparticles is disclosed. Particle size of the oxide core seeds is controlled and capped seeds are formed. The capping layer is desorbed by a thermally activated process and metal such as gold is chemically deposited on the core seeds in situ. This process can be repeated to produce multi-metal or different metal shells. A second capping layer is applied on the core/shell composite nanoparticles. In another step, the particles are sized by centrifuging to obtain a tightly controlled and narrow particle size distribution. The water-dispersibility of the particles is achieved by a thiol exchange reaction on the gold shell of the core/shell nanoparticles or by deposition of gold on ferritin-derived iron oxide cores in aqueous solution. Mono and multilayer thin films are assembled on different substrates using the core/shell particles and linking molecules.

A method and structure is provided for preventing wetting or bleed of an adhesive, such as an epoxy, onto noble metal wire bond pads on the surface of a dielectric substrate when attaching an I/C chip to the substrate. The method includes treating the wire bond pads with a chemical composition which prevents bleeding onto the surfaces of the wire bond pads by a component of the epoxy. The chemical composition is a chemical which will provide "Self-Assembled Monolayers" (SAMs) on the surface of the gold. These compositions are characterized by a molecule having at least one group, such as a mercaptan or disulfide, connected to a hydrocarbon moiety, such as a (CH2)x chain. The affinity of the thiol or sulfur-containing portion of the molecule chemically bonding with the noble metal provides a relatively strong attachment of the molecule to the metal surface. The hydrocarbon segment presents a surface on the noble metal that has the characteristics of the hydrocarbon portion of the molecule which has a low surface tension, and, thus, prevents wetting of the noble metal by an epoxy adhesive component.The SAMs, once they provide protection from the bleed of the die attach adhesives, self desorb during the wire bonding or soldering temperatures.
