发明名称 Structure for wiring reliability evaluation test and semiconductor device having the same
摘要 A test line (12) is formed between a pair of current sypplying terminals (11). A step pattern (14) composed of polysilicon or the like is formed below the test line (12) through an inter-layer insulation film. One of two sides of the step pattern (14) that extends along the longitudinal direction of the test line (12) is positioned therebelow so as to form a step extending in a direction of the test line. Thus, since electromigration tends to easily take place, the deterioration of the semiconductor device can be precisely evaluated.
