Abstract:
A metrology system is presented for measuring parameters of a structure. The system comprises: an optical system and a control unit. The optical system is configured for detecting light reflection of incident radiation from the structure and generating measured data indicative of angular phase of the detected light components corresponding to reflections of illuminating light components having different angles of incidence. The control unit is configured for receiving and processing the measured data and generating a corresponding phase map indicative of the phase variation along at least two dimensions, and analyzing the phase map using modeled data for determining one or more parameters of the structure.

Claim (Index 1):
A metrology system for measuring parameters of a structure, the metrology system being configured for performing Optical Critical Dimension (OCD) measurements and comprising:\n an optical system configured for detecting light reflection of incident radiation from the structure and generating measured data indicative of angular phase of the detected light components corresponding to reflections of illuminating light components having different angles of incidence, wherein the optical system comprises imaging and focusing lenses configured to create an image of a pupil of the optical system on a phase detector, thereby providing the measured data indicative of a two-dimensional phase map of the pupil, and a control unit configured for receiving and processing the measured data and generating a corresponding two-dimensional phase map of the pupil indicative of variation of the phase along at least one axes of two dimensions used in the two-dimensional phase map, analyzing the two-dimensional phase map and determining one or more parameters of the structure.
