| 摘要 |
A mostly copper-containing interconnect (126) overlies a semiconductor device substrate (100), and a transitional metallurgy structure (312, 508, 716, 806) that includes an aluminum-containing film (200, 506, 702, 802) contacts a portion of the mostly copper-containing interconnect. In one embodiment, the transitional metallurgy is formed over a portion of a bond pad (128). In an alternative embodiment, the transitional metallurgy includes an energy alterable fuse portion (710) that electrically contacts two conductive regions (712 and 714), and in yet another embodiment, the transitional metallurgy is formed over a copper-containing edge seal portion (809).
