摘要:
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 R 1 is a substituted or unsubstituted alkenyl group, R 2 may be present or not, and if present R 2 is a -(CH 2 ) n -SO 3 - 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.
摘要:
The present invention relates to a metallization method for solar cell substrates by electroplating wherein i) a resist is deposited onto at least one surface of a solar cell substrate and patterned, ii) a conductive seed layer is deposited onto the patterned resist and into the openings formed by the resist pattern, iii) a first metal or metal alloy is electroplated onto the conductive seed layer, and iv) those portions of the first metal or metal alloy layer deposited onto the patterned resist are removed.
