Abstract
A structure for arresting the propagation of cracks during the dicing of a semiconductor wafer into individual chips includes a monolithic metallic plate that traverses multiple dielectric layers peripheral to an active region of a chip. One or more metallic plates may be formed using lithography and electroplating techniques between the active device region and a peripheral kerf region, where each metallic plate includes a concave feature that faces the kerf region of the wafer.
