Publication number: 20240077308Abstract: A metrology system includes a radiation source, an adjustable diffractive element, an optical system, an optical element, and a processor. The radiation source generates radiation. The adjustable diffractive element diffracts the radiation to generate first and second beams of radiation. The first and second beams have first and second different non-zero diffraction orders, respectively. The optical system directs the first and second beams toward a target structure such that first and second scattered beams of radiation are generated based on the first and second beams, respectively. The metrology system adjusts a phase difference of the first and second scattered beams. The optical element interferes the first and second scattered beams at an imaging detector that generates a detection signal. The processor receives and analyzes the detection signal to determine a property of the target structure based on the adjusted phase difference.Type: ApplicationFiled: January 4, 2022Publication date: March 7, 2024Applicant: ASML Holding N.V.Inventors: Mohamed SWILLAM, Justin Lloyd KREUZER, Stephen ROUX, Michael Leo NELSON, Muhsin ERALP

Patent number: 11841626Abstract: An alignment method includes directing an illumination beam with a varying wavelength or frequency towards an alignment target, collecting diffraction beams from the alignment target and directing towards an interferometer. The alignment method also includes producing, by the interferometer, two diffraction sub-beams from the diffraction beams, wherein the diffraction sub-beams are orthogonally polarized, rotated 180 degrees with respect to each other around an alignment axis, and spatially overlapped. The alignment method further includes measuring interference intensity of the diffraction beams based on a temporal phase shift, wherein the temporal phase shift is a function of the varying wavelength or frequency of the illumination beam and a fixed optical path difference between the diffraction beams. The alignment method also includes determining a position of the alignment target from the measured interference intensity.Type: GrantFiled: July 22, 2020Date of Patent: December 12, 2023Assignee: ASML HOLDING N.V.Inventor: Muhsin Eralp

Patent number: 10753791Abstract: A multi-channel remote audio monitoring device based on a heterodyne interferometric laser Doppler vibrometer. The multi-channel remote audio monitoring device transmits two invisible laser beams to a reflecting surface being vibrated by sound sources in the proximity. Reflected beams constituting two channels are then received back and converted into audible signals for on-line listening and on-line storing. Aforementioned signals can also be processed for on-line noise reduction purposes through a graphical user interface and a filtering module.Type: GrantFiled: January 26, 2016Date of Patent: August 25, 2020Assignee: TUBITAKInventors: Yildirim Bahadirlar, Emin Ça{hacek over (g)}atay Güler, Selami Şahin, Muhsin Eralp, Kamer Kayaer, Cenk Eryilmaz
