  • Patent number: 11512405
    Abstract: The present invention concerns a metal or metal alloy deposition composition, particularly a copper or copper alloy deposition composition, for electrolytic deposition of a metal or metal alloy layer, particularly for electrolytic deposition of a copper or copper alloy layer, comprising at least one type of metal ions to be deposited, preferably copper ions, and at least one imidazole based plating compound. The present invention further concerns a method for preparation of the plating compound, the plating compound itself and its use in a metal or metal alloy deposition composition. The inventive metal or metal alloy deposition composition can be preferably used for filling recessed structures, in particular those having higher diameter to depth aspect ratios.

  • Patent number: 11091849
    Abstract: An aqueous bath for filling a vertical interconnect access or trench of a work piece with nickel or a nickel alloy, the bath comprising a source of nickel ions, and optionally a source of ions of at least one alloying metal, at least one buffering agent, at least one of a dimer of a compound of formula (I) or mixtures thereof wherein R1 is a substituted or unsubstituted alkenyl group, R2 may be present or not, and if present R2 is a —(CH2)n—SO3? group, wherein n is an integer in the range of 1-6, and wherein one or more of the hydrogens in the group may be replaced by a substituent, preferably hydroxide; and a method for filling a vertical interconnect access or trench of a work piece with nickel or a nickel alloy with said aqueous bath.

  • Patent number: 9551080
    Abstract: The present invention relates to aqueous acidic plating baths for copper and copper alloy deposition in the manufacture of printed circuit boards, IC substrates, semiconducting and glass devices for electronic applications. The plating bath according to the present invention comprises copper ions, at least one acid and an ureylene polymer comprising amino residues on both termini and which is free of organically bound halogen. The plating bath is particularly useful for filling recessed structures with copper and build-up of pillar bump structures.
