Abstract: A conditioning element for trueing and dressing a polishing pad used in a chemical mechanical polishing process (CMP) in connection with the manufacture of semi-conductors is provided with a relatively thin protective coating comprising a material resistant to corrosive attack by CMP slurry compositions, including those particularly well-suited to resist the harsher highly acidic slurry compositions. The CMP conditioning disk comprises a substrate having a surface carrying a monolayer of superabrasive particles braze bonded to the disk and a relatively thin liquid impermeable protective coating which is applied over the surface of the braze bond material and abrasive particles.

Abstract: Electroless gold plating baths for plating metallized ceramics wherein the bath comprises (a) alkali metal gold cyanide, (b) alkali metal fluoride, and (c) alkali metal hydroxide. The baths may optionally contain a buffering agent and/or ammonium hydroxide and/or an organic chelating agent. The metallized ceramics contain tungsten, molybdenum, electroless nickel, copper and the like. The gold constituent in the alkali metal gold cyanide may be monovalent, trivalent or mixtures thereof. The method of utilizing such electroless or autocatalytic plating baths is also described and claimed.

Abstract: An electroless plating process for depositing gold on substrates, such as metal and metallized substrates, which involves immersing the substrates in an electroless plating bath composed of a trivalent gold complex, an organic carboxylic acid, and/or a mineral acid sufficient in amount so that the pH of the bath will range from about 0.1 to 6.0. The process of utilizing said electroless bath to deposit gold on the aforementioned substrates is also disclosed and claimed.

Abstract: Improved electroless or autocatalytic gold plating baths wherein the gold ingredient is a water soluble trivalent gold component selected from an alkali metal auricyanide, an alkali metal aurihydroxide, and an alkali metal aurate. The bath contains an amino borane, an alkali metal borohydride, or an alkali metal cyanoborohydride as the reducing agent; an alkaline agent such as an alkali metal hydroxide; and an alkaline buffering agent. Optionally, the bath may contain added alkali metal cyanide. The method of utilizing such electroless or autocatalytic plating bath for depositing gold on metallic substrates such as gold, copper, copper alloys, electroless copper, electroless nickel, nickel, nickel alloys, etc. and on a non-metallic substrates is also described and claimed.
