    Abstract: A method and system are presented for use in controlling the processing of a structure. First measured data is provided being indicative of at least one of the following: a thickness (d2) of at least one layer (L2) of the structure W in at least selected sites of the structure prior to the processing of the structure, and a surface profile of the structure prior to said processing. An optical measurement is applied to at least the selected sites of the structure after said processing and second measured data is generated being indicative of at least one of the following: a thickness of the processed structure (d′) and a surface profile of the processed structure, The second measured data is analyzed by interpreting it using the first measured data to thereby determine a thickness (d′1 or d′2) of at least one layer of the processed structure. This determined thickness is thus indicative of the quality of said processing.

    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.

    Abstract: A method and system are presented for optical measurements in multi-layer structures to determine the properties of at least some of the layers. The structure is patterned by removing layer materials within a measurement site of the structure from the top layer to the lowermost layer of interests. Optical measurements are sequentially applied to the layers, by illuminating a measurement area in the layer under measurements, when the layer material above said layer under measurements is removed, thereby obtaining measured data portions for the at least some of the layers, respectively. The properties of each of the at least some layers are calculated, by analyzing the measured data portion of the lowermost layer, and then sequentially interpreting the measured data portions of all the other layers towards the uppermost layer, while utilizing for each layer the calculation results of the one or more underlying layers.

    Abstract: A method and system are presented for monitoring a process sequentially applied to a stream of substantially identical articles by a processing tool, so as to terminate the operation of the processing tool upon detecting an end-point signal corresponding to a predetermined value of a desired parameter of the article being processed. The article is processed with the processing tool. Upon completing the processing in response to the end-point signal generated by an end-point detector continuously operating during the processing of the article, integrated monitoring is applied to the processed article to measure the value of the desired parameter. The measured value of the desired parameter is analyzed to determine a correction value thereof to be used for adjusting the end-point signal corresponding to the predetermined value of the desired parameter for terminating the processing of the next article in the stream.
