    Abstract: An optical system is presented for use in a measurement system for measuring in patterned structures, which is particularly useful controlling processing of the structure progressing on a production line. The system comprises an illuminator unit producing illuminating light to be directed to the structure to produce returned light, a detector unit comprising an imaging detector and a spectrophotometer detector, and a light directing assembly. The light directing assembly defines first and second optical paths for the light propagation. The optical elements accommodated in the first optical path affect the light to provide a relatively small measuring area of the structure's plane. The second optical path is located outside the first optical path, the light propagation through the second optical path providing a relatively large measuring area, as compared to that of the first optical path.

    Abstract: A method and system are presented for use in optical processing of an article by VUV radiation. The method comprises: localizing incident VUV radiation propagation from an optical head assembly towards a processing site on the article outside the optical head assembly and localizing reflected VUV radiation propagation from said processing site towards the optical head assembly by localizing a medium, non-absorbing with respect to VUV radiation, in within the light propagation path in the vicinity of said site outside the optical head assembly. The level of the medium is controlled by measuring the reflected VUV radiation.

    Abstract: A method and system are presented for determining a line profile in a patterned structure, aimed at controlling a process of manufacture of the structure. The patterned structure comprises a plurality of different layers, the pattern in the structure being formed by patterned regions and un-patterned regions. At least first and second measurements are carried out, each utilizing illumination of the structure with a broad wavelengths band of incident light directed on the structure at a certain angle of incidence, detection of spectral characteristics of light returned from the structure, and generation of measured data representative thereof. The measured data obtained with the first measurement is analyzed, and at least one parameter of the structure is thereby determined. Then, this determined parameter is utilized, while analyzing the measured data obtained with the second measurements enabling the determination of the profile of the structure.

    Abstract: Alignment of layers during manufacture of a multi-layer sample is controlled by applying optical measurements to a measurement site in the sample. The measurement site includes two diffractive structures located one above the other in two different layers, respectively. The optical measurements include at least two measurements with different polarization states of incident light, each measurement including illuminating the measurement site so as to illuminate one of the diffractive structures through the other. The diffraction properties of the measurement site are indicative of a lateral shift between the diffractive structures. The diffraction properties detected are analyzed for the different polarization states of the incident light to determine an existing lateral shift between the layers.
