Abstract
Spectroscopic ellipsometry technology has extensive applications in semiconductor metrology. Compared with spectroscopic ellipsometry, the Mueller matrix ellipsometry can acquire more useful information about the sample. In this paper, we present the construction of Mueller measurement equipment for 300 mm integrated circuit production line application and demonstrate the abilities of the equipment for accurate profile characterization of nanoscale structure. Mueller matrix ellipsometry may become a powerful technology for advanced technology node measurement in semiconductor device manufacturing applications.
