Publication number: 20240085333Abstract: A method, a system, and a non-transitory computer readable medium for accurate Raman spectroscopy. The method may include executing at least one iteration of the steps of: (i) performing, by an optical measurement system, a calibration process that comprises (a) finding a misalignment between a region of interest defined by a spatial filter, and an impinging beam of radiation that is emitted from an illuminated area of a sample, the impinging beam impinges on the spatial filter; and (b) determining a compensating path of propagation of the impinging beam that compensates the misalignment; and (ii) performing a measurement process, while the optical measurement system is configured to provide the compensating path of propagation of the impinging beam, to provide one or more Raman spectra.Type: ApplicationFiled: August 18, 2023Publication date: March 14, 2024Applicant: NOVA LTD.Inventors: Elad Schleifer, Yonatan Oren, Amir Shayari, Eyal Hollander, Valery Deich, Shimon YALOV, Gilad BARAK

Publication number: 20240019375Abstract: A method, a system, and a non-transitory computer readable medium for Raman spectroscopy. The method may include determining first acquisition parameters of a Raman spectroscope to provide a first acquisition set-up, the determining is based on at least one expected radiation pattern to be detected by a sensor of the Raman spectroscope as a result of an illumination of a first area of a sample, the first area comprises a first nano-scale structure, wherein at least a part of the at least one expected radiation pattern is indicative of at least one property of interest of the first nano-scale structure of the sample; wherein the first acquisition parameters belong to a group of acquisition parameters; setting the Raman spectroscope according to the first acquisition set-up; and acquiring at least one first Raman spectrum of the first nano-scale structure of the sample, while being set according to the first acquisition set-up.Type: ApplicationFiled: September 14, 2021Publication date: January 18, 2024Applicant: NOVA LTD.Inventors: Eyal Hollander, Gilad BARAK, Elad Schleifer, Yonatan OREN, Amir Shayari

Patent number: 11868054Abstract: A measurement system is provided for use in optical metrology measurements. The measurement system comprises a control system which processes raw measured data indicative of spectral interferometric signals measured on a sample in response to illuminating electromagnetic field incident onto a top portion of the sample and comprising at least one spectral range to which said sample is substantially not absorbing.Type: GrantFiled: February 24, 2021Date of Patent: January 9, 2024Assignee: Nova Ltd.Inventors: Gilad Barak, Amir Shayari
