Abstract
Integrated circuits and methods for fabricating integrated circuits are provided. In one example, a method for fabricating an integrated circuit includes fabricating a crack-stop structure that extends through a plurality of metallization layers above a semiconductor substrate. The plurality of metallization layers includes a first metallization layer and a second metallization layer that overlies the first metallization layer. Fabricating the crack-stop structure includes forming a first via-bar overlying and coupled to a first metal line of the first metallization layer that is disposed in a first ILD layer of dielectric material. The first via-bar is disposed in a second ILD layer of dielectric material and has a first width. A second metal line of the second metallization layer that is in the second ILD layer is formed overlying and coupled to the first via-bar. The second metal line has a second width that is from about 1 to about 5 times the first width.
