摘要
By providing vias of increased mass flow blocking capability next to respective line segments of an electromigration test structure, the reliability of respective assessments may be enhanced, since electromigration-induced void formation in the test line segment under consideration may be efficiently decoupled from metal diffusion of neighboring test areas of the test structure.
