    Abstract: A process control system is provided for use with a processing tool for thin film patterning by a material removal processing system. The system includes an optical end-point detector operable within a working area defined by the processing tool when the processing tool is applied to an article, the optical end-point detector performing in-situ measurements of parameters of patterned thin film on the article. An optical integrated monitoring tool is installed with the processing tool and operable outside the working area for measuring parameters of the patterned thin film on the article. A control unit is connected to the end-point detector and to the integrated monitoring tool, and includes processing and computational intelligence responsive to data received from the end-point detector and to the measured data received from the integrated monitoring tool for analyzing data and generating a signal for terminating the patterning of the thin film on the article.

    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.

    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.
