Disclosed is a method of plating a substrate with a metal using an autocatalytic electroless plating bath wherein the bath is operated above its cloud point temperature such that at least two phases are present in the bath. An autocatalytic electroless plating bath for coating silver metal is also described. A method for autocatalytic plating of silver metal directly onto a silicon surface without the need for an intervening layer of metal is also disclosed. The deposits of silver obtained are uniform, non-porous and have electrical properties . The technique can be applied for different processes and bath formulations i.e. different metals, complexing agents and reducing agents .
摘要:
A method for electroless plating of metal on a laser-patterned substrate. A substrate is provided on which both a thermal imaging layer and catalytic layer are deposited. On exposure to a laser beam, sufficient levels of radiation are converted to heat in the thermal imaging layer to render the exposed regions of the adjacent catalytic layer inactive. The laser-patterned substrate is then exposed to a reaction solution which initiates the growth of a metal film on the unexposed regions of the catalytic layer.

A method for producing a substrate with black film is provided, comprising forming a dull plating film on a surface of a substrate, forming an electroless plating film containing a sulfur or nitrogen compound on the surface of the plating film, and forming a black film on the surface of the electroless plating film. This substrate with black film is used for devices which generate heat due to sliding or friction or generate/ accumulate heat due to a chemical reaction, such as semiconductor device, vacuum device, rotating device and heat exchanger, and the black film has excellent heat radiating properties with an emissivity of 0.8 or more. Also, this substrate with black film has high corrosion resistance against halogen-type corrosive gases and exhibits excellent release gas properties and corrosion resistance in vacuum devices.
摘要:
Methods and apparatus are provided for forming a metal or metal silicide layer by an electroless deposition technique. In one aspect, a method is provided for processing a substrate including depositing an initiation layer on a substrate surface, cleaning the substrate surface, and depositing a conductive material on the initiation layer by exposing the initiation layer to an electroless solution. The method may further comprise etching the substrate surface with an acidic solution and cleaning the substrate of the acidic solution prior to depositing the initiation layer. The initiation layer may be formed by exposing the substrate surface to a noble metal electroless solution or a borane-containing solution. The conductive material may be deposited with a borane-containing reducing agent. The conductive material may be used as a passivation layer, a barrier layer, a seed layer, or for use in forming a metal silicide layer.
摘要:
A metal plating method which is characterized in that it comprises pretreating an article to be plated with a pretreating agent prepared by admixing a solution containing a metal exhibiting a catalytic activity in depositing a plating metal such as copper and nickel from an electroless plating solution onto the surface to be plated with a solution of a silane coupling agent having a functional group capable of capturing the metal, to thereby allow the silane coupling agent to capture the metal, and then adding a reducing agent, and thereafter carrying out an electroless plating. A desired metal can be plated on a surface thus electroless-plated.
