Abstract:
The invention relates to an aqueous plating bath composition and a method for depositing a palladium layer by electroless plating onto a substrate. The aqueous plating bath composition according to the invention comprises a source for palladium ions, a reducing agent for palladium ions and a cyanide group containing aromatic compound. The aqueous plating bath composition according to the invention has an improved stability against undesired decomposition due to the cyanide group containing aromatic compounds while keeping the deposition rate for palladium at the desired satisfying value. The aqueous plating bath composition has also a prolonged life time. The cyanide group containing aromatic compounds of the invention allow for adjusting the deposition rate to a satisfying range over the bath life time and for electrolessly depositing palladium layers at lower temperatures.

Claim (Index 1):
An aqueous plating bath composition for electroless deposition of palladium, comprising\n (i) at least one source for palladium ions, (ii) at least one reducing agent for palladium ions, and (iii) at least one cyanide group containing aromatic compound selected from compounds according to Formula (I), salts thereof, and mixtures of the aforementioned; and/or at least one cyanide group containing aromatic compound selected from compounds according to Formula (II), salts thereof, and mixtures of the aforementioned; wherein R1, R2, R3, R4, R5, R6 are selected independently of each other from the group consisting of R7, \u2014H, C1 to C6 alkyl group, C1 to C6 alkoxy group, amino, aldehyde, mercapto, sulfide group, halogen, allyl, vinyl, ethynyl, propynyl, 1-butynyl, 2-butynyl, 2-ethynylbenzene, phenyl, pyridyl, and naphthyl groups; wherein at least one of R1 to R6 is R7; wherein R7 is a moiety according to Formula (III), wherein each R8 is selected independently from the group consisting of \u2014H, C1 to C6 alkyl group, hydroxyl, C1 to C6 alkoxy group, amino, mercapto, and sulfide group; wherein n is an integer ranging from 0 to 4; and wherein X is selected from N and C\u2014R13; wherein Y is selected from N and C\u2014R14; wherein at least one of X or Y is N; wherein R9, R10, R11, R12, R13, R14 are selected independently of each other from the group consisting of R15, \u2014H, C1 to C6 alkyl group, hydroxyl, C1 to C6 alkoxy group, amino, aldehyde, carboxyl, ester, sulfonic acid, mercapto, sulfide group, halogen, allyl, vinyl, ethynyl, propynyl, 1-butynyl, 2-butynyl, 2-ethynylbenzene, phenyl, pyridyl, and naphthyl groups; wherein at least one of R9 to R14 is R15; wherein R15 is a moiety according to Formula (IV), wherein each R16 is selected independently from the group consisting of \u2014H, C1 to C6 alkyl group, hydroxyl, C1 to C6 alkoxy group, amino, mercapto, and sulfide group; wherein m is an integer ranging from 0 to 4, and wherein if at least one of X or Y is N, R15 is in the ortho or meta position in relation to N within the aromatic ring according to Formula (II).
