A unified test structure which is applicable for all levels of a semiconductor device including a current path chain having a first half chain and a second half chain, wherein each half chain comprises lower metallization segments, upper metallization segments, an insulating layer between the lower metallization segments and the upper metallization segments, and connection segments. Each of the connection segments is electrically connected to a contact region of one of the lower metallization segments and to a contact region of one of the upper metallization segments to thereby electrically connect the respective lower metallization segment and the respective upper metallization segment, and the first half chain and the second half chain are of different configuration. |
