  • Patent number: 10508207
    Abstract: The invention relates to a composition and a process for the deposition of conductive polymers on dielectric substrates. In particular, the invention relates to a composition for the formation of electrically conductive polymers on the surface of a dielectric substrate, the composition comprising at least one polymerizable monomer which is capable to form a conductive polymer, an emulsifier and an acid, characterized in that the composition comprises at least one metal-ion selected from the group consisting of lithium-ions, sodium-ions, aluminum-ions, beryllium-ions, bismuth-ions, boron-ions, indium-ions and alkyl imidazolium-ions. The acid is typically a high molecular weight polymeric acid having molecular weight of at least 500,000 Da including, for example, polystyrene sulfonic acid having a molecular weight of approximately 1,000,000 Da.
    Type: Grant

  • Patent number: 7713859
    Abstract: A process for forming a solder bump on an under bump metal structure in the manufacture of a microelectronic device comprising exposing the under bump metal structure to an electrolytic bath comprising a source of Sn2+ ions, a source of Ag+ ions, a thiourea compound and/or a quaternary ammonium surfactant; and supplying an external source of electrons to the electrolytic bath to deposit a Sn—Ag alloy onto the under bump metal structure.

  • Publication number: 20050268991
    Abstract: A method for enhancing corrosion resistance of a tin-based surface on a workpiece involving contacting the tin-based surface with a composition comprising a phosphonic acid compound and water to form a phosphorus-based film over the tin-based coating thereby inhibiting corrosion of the tin-based surface. Phosphonic acid containing compositions having a concentration up to about 30 vol. % of an organic solvent, and water.
