Abstract: A crack stop (28) for low K dielectric materials of an integrated circuit (IC) formed on an IC chip using metal interconnects which do not form a self-passivating oxide layer, such as copper or silver interconnects, in a low-K dielectric material to prevent damage to the active area of the IC chip caused by chipping and cracking formed along peripheral edges of the IC chip during a dicing operation. A moisture barrier or edge seal (12) is formed as a metal stack positioned along the outer peripheral edges of the active area of the IC chip. The crack stop is formed by at least one trench or groove positioned outside of the moisture barrier/edge seal on the outer periphery of the IC chip.

Abstract translation: 使用金属互连在集成电路(IC)上形成集成电路(IC)的低K电介质材料的裂缝阻挡(28),所述金属互连在低K电介质中不形成自钝化氧化物层(例如铜或银互连) 材料以防止在切割操作期间由于沿着IC芯片的外围边缘形成的碎裂和破裂而导致对IC芯片的有源区域的损坏。 防潮层或边缘密封件(12)形成为沿着IC芯片的有效区域的外周边缘定位的金属堆叠。 通过位于IC芯片的外周上的防潮/边缘密封件外侧的至少一个沟槽或槽来形成止裂件。
