ENERGY-ABSORBING STABLE GUARD RING

摘要

An integrated circuit (IC) (400) is provided. The IC includes a silicon substrate and at least one dielectric layer (403) and a metal layer (402) formed upon the silicon substrate. The at least one dielectric layer (403) and metal layer (402) form a die active area (401). The IC further includes a guard ring (404), enclosing the die active area (401). The guard ring (404) has zig-zag shaped portions at corners (451) thereof.
