dc.description.abstract | The electroless nickel plating on an aluminum input/output (I/O) pad was investigated. The aluminum pad was pretreated in a zincate solution prior to electroless nickel plating. Zinc particles on the aluminum pad gave a good adherent nickel layer. The adhesion and uniformity of zinc on the aluminum is the key factor in under-bump metallurgy (UBM). The electrode potential changes with and without zinc ions in the bath were measured to analyze the sequence of two competing reactions: zinc deposit and hydrogen evolution. The relationship between aluminum dissolution and the ratio of zinc and NaOH was investigated. The electroless nickel deposition rate was dependent on bath composition. The effects of complexing ligand and additive on the nickel deposit were analyzed. Electrode potential changes were measured with time to confirm nucleation and grain growth. Adhesion of the UBM was related to zinc-particle dissolution and nickel nucleation. The uniform nickel UBM was fabricated on a real Al I/O pad. | - |
