Abstract

PURPOSE:To obtain a nonaq. Al plating soln. for an electronic material giving a plating film contg. no halogen element by adding Al carboxylate or an Al carbonyl compd. as an org. Al compd. contg. H, C, N, O and Al as the constituent elements of a functional group and a reducing agent to an org. solvent. CONSTITUTION:A nonaq. Al plating soln. contg. Al carboxylate or an Al carbonyl compd. such as Al acetate or acetylacetone Al as an org. Al compd. having H, C, N, O and Al as the constituent elements of a functional group and an alkali metal hydride or borohydride or a hydrogenated Al compd. such as HLiAl or NaBH4 as an Al ion reducing agent in one or more kinds of org. solvents selected among alcohols, ethers, carboxylic acids, furans and lactones is used as an Al electroplating soln. for an electronic material, etc. An Al plating film not contg. harmful halogen elements such as Cl is obtd.

By making the terminal group of the aluminum compound and the terminal group of the organic solvent the same or similar, affinity can be strengthened and solubility can be increased. This makes it possible to reduce the resistance of the aluminum plating solution, facilitate energization, and improve electrolytic efficiency.
