发明名称 Bump structure, method of forming bump structure, and semiconductor apparatus using the same
摘要 A bump structure includes a squashed ball provided on an electrode pad, and a wire provided on the squashed ball. The wire is a wire loop that is loop-shaped and is formed so as to protrude from an end part of the squashed ball. This provides high bonding reliability between a bonding pad and the bump structure.
