Abstract
A semiconductor device that includes a substrate having integrated circuits; a plurality of metallization layers on the substrate, the plurality of metallization layers having a peripheral region adjacent to a kerf region of the semiconductor device and containing a crack stop structure extending through the plurality of metallization layers; a trench extending through the plurality of metallization layers and adjacent to the crack stop structure, the trench filled with a material that creates compressive stresses between the filled trench and the adjacent metallization layers to form a compressive zone adjacent to the crack stop structure. Also disclosed is a method for forming the semiconductor device.
