Abstract. We propose novel stress metrology technique for measurement of local values stress tensor components in the coated wafers. New metrology is based on fiber-optic low coherence interferometry and can be applied to study stress not only in semicondiuctor wafers but in wide variety applications spanning from semiconductor to construction industry where measurements of plates covered by thin film encountered in flat panel displayes, solar cells, modern windows.
