Paper Abstract

The new method and new set-up are developed for accurate (approximately 1 divided by 5%) measurement of the width of submicrometer structures (slit, groove, wire). The method is based on the measurement of the shifts of the interference fringes depending on the width of structure. The interference pattern is obtained by interference of the diffracted beams in a two- beam interferometer. The comparison of the shifts of the fringes from reference and investigated width is made.
