One method includes detecting defects on a wafer by applying a threshold to output generated by a detector in a first scan of the wafer and determining values for features of the detected defects. The method also includes automatically ranking the features, identifying feature cut-lines to group the defect into bins, and, for each of the bins, determining one or more parameters that if applied to the values for the features of the defects in each of the bins will result in a predetermined number of the defects in each of the bins. The method also includes applying the one or more determined parameters to the output generated by the detector in a second scan of the wafer to generate a defect population that has a predetermined defect count and is diversified in the values for the features. | 05-05-2016 |

20150049931 | SIMULTANEOUS HIGH SPATIAL LOW TEMPORAL RESOLUTION MAGNETIC RESONANCE (MR) SEQUENCE FOR DYNAMIC CONTRAST ENHANCED (DCE) MAGNETIC RESONANCE IMAGING (MRI) - The invention discloses a dual magnetic resonance imaging method for simultaneously acquiring a first and a second time series of MR images wherein the temporal resolution of the first time series of images is larger than that of the second time series while the spatial resolution of the first time series of images is smaller than that of the second time series. Accordingly, in the context of DCE-MRI, the first time series can be used to determine the arterial input function (AIF) while the second time series can be used to determine the concentration time course in the tissue of interest, e.g. in a vessel wall. Therefore, both the AIF and the tissue time course can be acquired with their optimal dynamic signal range. | 02-19-2015 |
