| 摘要 |
The invention includes a method of electroless deposition of nickel over an aluminum-containing material. A mass is formed over the aluminum-containing material, with the mass predominantly comprising a metal other than aluminum. The mass is exposed to palladium, and subsequently nickel is electroless deposited over the mass. The invention also includes a method of electroless deposition of nickel over aluminum-containing materials and copper-containing materials. The aluminum-containing materials and copper-containing materials are both exposed to palladium-containing solutions prior to electroless deposition of nickel over the aluminum-containing materials and copper-containing materials. Additionally, the invention includes a method of forming a solder bump over an aluminum-containing material.
