Patent number: 10545104Abstract: Methods and systems for performing overlay and edge placement errors of device structures based on x-ray diffraction measurement data are presented. Overlay error between different layers of a metrology target is estimated based on the intensity variation within each x-ray diffraction order measured at multiple, different angles of incidence and azimuth angles. The estimation of overlay involves a parameterization of the intensity modulations of common orders such that a low frequency shape modulation is described by a set of basis functions and a high frequency overlay modulation is described by an affine-circular function including a parameter indicative of overlay. In addition to overlay, a shape parameter of the metrology target is estimated based on a fitting analysis of a measurement model to the intensities of the measured diffraction orders. In some examples, the estimation of overlay and the estimation of one or more shape parameter values are performed simultaneously.Type: GrantFiled: April 28, 2016Date of Patent: January 28, 2020Assignee: KLA-Tencor CorporationInventors: John Hench, Andrei V.

Patent number: 10357221Abstract: A method for calibrating detectors in a CT scanner, wherein the new calibration process uses a combination of slab-based and water-based calibrations. By combining both calibrations, the complexity of each procedure can be reduced which will reduce restrictions on the quality of detectors used in the scanner. The slabs can be made out of commercially available material such as acrylic, and they will require no special treatment. Combining both calibrations also reduces the number of water phantoms needed for the calibration and the complexity of the calibration algorithm. Furthermore, the slabs can be shaped based on the scanner geometry so as to optimize the slab-based calibration step.Type: GrantFiled: August 21, 2015Date of Patent: July 23, 2019Assignee: Samsung Electronics Co., Ltd.Inventors: Ibrahim Bechwati, Eric Bailey, Geethika Weliwitigoda
