Abstract

After a barrier film is formed on a pad electrode, Ni particles having a diameter of 2 &mgr;m or less are selectively deposited on the barrier film, thereby forming a Ni fine particle film. Then, a bump electrode made of a solder ball is provided on the pad electrode through the Ni fine particle film. Thereafter, the bump electrode is melted by a heat treatment to join the Ni fine particle film to the bump electrode. Thus, a bump electrode structure is finished.
