| 摘要 |
The prevent invention relates to a terminal structure including a base material (10), an electrode (20) formed on the material, an insulating sheath layer (30) formed on the electrode and having an opening exposing at least part of the electrode, an under bump metal layer (70) charging the opening and covering part of the insulating sheath layer, and a dome bump (85) covering the under bump metal layer. For a section according to a laminating direction, the under bump metal layer is protruding to the bump. The thickness (Tu0) of the under bump metal layer for the center of the opening is thicker than the thickness (Tu1) of the under bump metal layer for the section of the opening. |
