发明名称 METHODS OF QUANTIFYING VARIATIONS RESULTING FROM MANUFACTURING-INDUCED CORNER ROUNDING OF VARIOUS FEATURES, AND STRUCTURES FOR TESTING SAME
摘要 The present invention is directed to methods of quantifying variations resulting from manufacturing-induced corner rounding of various features, and structures for testing same. In one illustrative embodiment, the method includes forming a plurality of test structures on a semiconducting substrate, each of the test structures having at least one physical dimension that varies relative to the other of the plurality of test structures, at least some of the test structures exhibiting at least some degree of manufacturing-induced corner rounding, forming at least one reference test structure, performing at least one electrical test on the plurality of test structures and on the reference test structure to thereby produce electrical test results, and analyzing the test results to determine an impact of the manufacturing-induced corner rounding on the performance of the plurality of test structures.
