TWO-PHOTON FLUORESCENCE MICROSCOPY AT EXTREMELY LOW EXCITATION INTENSITY
The present disclosure pertains to two-photon microscopy, and specifically to methods and systems for optimizing the performance of entangled two-photon absorption (ETPA) microscopy. An ETPA microscope is described with time delay tunability to optimize the coincidence of entangled photons on a sample. The optimization allows for increased two-photon absorption by the sample, resulting in increased luminescence of the sample. The ETPA microscopy systems and methods described allow for nonlinear imaging using excitation energy intensities six orders of magnitude lower than comparable two-photon absorption microscopy techniques using classical light.

SEMICONDUCTOR WAFER INSPECTION USING CARE AREA GROUP-SPECIFIC THRESHOLD SETTINGS FOR DETECTING DEFECTS
In the methods and systems, optical images of inspection care areas on a semiconductor wafer are acquired and analyzed to detect defects. However, during this analysis, the same threshold setting is not used for all inspection care areas. Instead, care areas are grouped into different care area groups, based on different design layouts and properties. Each group is associated with a corresponding threshold setting that is optimal for detecting defects in the inspection care areas belonging to that group. The assignment of the care areas to the different groups and the association of the different threshold settings with the different groups are noted in an index. This index is accessible during the analysis and used to ensure that each of the inspection care areas in a specific care area group is analyzed based on a corresponding threshold setting that is optimal for that specific care area group.
METHOD FOR SIMULTANEOUS CAPTURE OF IMAGE DATA AT MULTIPLE DEPTHS OF A SAMPLE
A novel method is disclosed to allow for the simultaneous capture of image data from multiple depths of a volumetric sample. The method allows for the seamless acquisition of a 2D or 3D image, while changing on the fly the acquisition depth in the sample. This method can also be used for auto focusing. Additionally this method of capturing image data from the sample allows for optimal efficiency in terms of speed, and light sensitivity, especially for the herein mentioned purpose of 2D or 3D imaging of samples when using a tilted configuration as depicted in FIG. 2. The method may be particularly used with an imaging sensor comprising a 2D array of pixels in an orthogonal XY coordinate system where gaps for electronic circuitry are present. Also other imaging sensor may be used. Further, an imaging device is presented which automatically carries out the method.
