摘要
Improved methods and systems for inspection imaging for holographic or interferometric semiconductor test and evaluation through all phases of device development and manufacture. Specifically, systems and methods are disclosed for extending the range of optical holographic interferometric inspection for testing and evaluating microelectronic devices and determining the interplay of electromagnetic signals and dynamic stresses to the semiconductor material are provided in which an enhanced imaging method provides continuous and varying the magnification of the optical holographic interferometric images over a plurality of interleaved optical pathways and imaging devices. Analysis of one or more holographic interference patterns displays internal and external stresses and the various effects of such stresses upon the operating characteristics of features within the features, interior structures or within the internal surfaces of the semiconductor device at any stage of development or manufacture.
