    摘要: Via stack structures are disclosed. In one embodiment, a structure includes a via stack including: a first substantially cross-shaped line in a first dielectric layer; a second substantially cross-shaped line set in a second dielectric layer, and a via stud coupling the first substantially cross-shaped line to the second substantially cross-shaped line. In another embodiment, a structure includes a first via stack, and a second via stack, wherein the first via stack and the second via stack extend in a divergent manner from one another. Each via stack structure is useful for support, for example, in under wire bond applications. The via stack structures can be mixed with other via stack structures and selectively placed within a layout to replace conventional metal plate and via stud array configurations.
