摘要： An integrated circuit substrate containing an electrical probe pad structure over, and on both sides of, a dicing kerf lane. The electrical probe pad structure includes metal crack arresting strips adjacent to the dicing kerf lane. A metal density between the crack arresting strips is less than 70 percent. An electrical probe pad structure containing metal crack arresting strips, with a metal density between the crack arresting strips less than 70 percent. A process of forming an integrated circuit by forming an electrical probe pad structure over a dicing kerf lane adjacent to the integrated circuit, such that the electrical probe pad structure has metal crack arresting strips adjacent to the dicing kerf lane, and performing a dicing operation through the electrical probe pad structure.

摘要： An integrated circuit containing a crack deflecting scribe seal which separates an interior region of the integrated circuit from a scribeline immediately outside the integrated circuit and a method of forming the same. The crack deflecting scribe seal includes continuous metal layers and continuous contacts and continuous vias between the continuous metal layers. The continuous metal layers do not extend past the continuous contacts and continuous vias. The continuous contacts and continuous vias are recessed from edges of the underlying continuous metal layers on the scribeline side of the scribe seal, providing an angled outer surface on the scribe seal which may desirably terminate crack propagation or deflect crack propagation upward to a top surface of the scribeline or the crack deflecting scribe seal.
