Abstract:
Reaction products of guanidine compounds or salts thereof, polyepoxide compounds and polyhalogen compounds may be used as levelers in metal electroplating baths, such as copper electroplating baths, to provide good throwing power. Such reaction products may plate with good surface properties of the metal deposits and good physical reliability.
Abstract:
A method for forming a polymerized film on a surface of a non-conductive material and subsequently forming an electroless metal plating film on the surface is described. The method includes the step of contacting the surface of the material with a solution including (A) an amine compound having at least two functional groups, where at least one of the functional groups is an amino group, and (B) an aromatic compound having at least one hydroxyl group on the aromatic ring.
Abstract:
Aqueous catalysts of nanoparticles of precious metals and stabilizers of flavonoid derivatives are used to electrolessly plate metal on non-conductive substrates. Such substrates include printed circuit boards.
Abstract:
Sulfonamide based polymers are reaction products of sulfonamides and epoxides. The polymers may be used as levelers in copper electroplating baths, to provide good throwing power. Such reaction products may plate copper or copper alloys with good surface properties and good physical reliability.
Abstract:
Reaction products of halogenated pyrimidines and nucleophilic linker units are included in metal electroplating baths to provide good throwing power. The electroplating baths can be used to plate metal, such as copper, tin and alloys thereof on printed circuit boards and semiconductors and fill through-holes and vias.
Abstract:
This invention relates to copper plating baths containing a leveling agent that is a reaction product of one or more of certain cyclodiaza-compounds with one or more epoxide-containing compounds useful to deposit copper on the surface of a conductive layer. Such plating baths deposit a copper layer that is substantially planar on a substrate surface across a range of electrolyte concentrations. This invention also relates to methods of depositing copper layers using such copper plating baths.
Abstract:
Reaction products of primary and secondary diamines and bisanhydrides are included as additives in metal electroplating baths. The metal electroplating baths have good throwing power and deposit metal layers having substantially planar surfaces. The metal plating baths may be used to deposit metal on substrates with surface features such as through-holes and vias.
Abstract:
Reaction products of one or more amino acids and one or more epoxies are included in copper and copper alloy electroplating baths to provide good throwing power. Such reaction products may plate copper and copper alloys with good surface properties and good physical reliability.
