Abstract:
In the scanning molecule counting method detecting light of a light-emitting particle in a sample solution using a confocal or multiphoton microscope, there is provided an optical analysis technique enabling the scanning in a sample solution with moving a light detection region in a broader area or along a longer route while making the possibility of detecting the same light-emitting particle as different particles as low as possible and remaining the size or shape of the light detection region unchanged as far as possible. In the inventive optical analysis technique, there are performed detecting light from the light detection region and generating time series light intensity data during moving the light detection region along the second route whose position is moved along the first route, and thereby, the signal indicating light from each light-emitting particle in a predetermined route is individually detected using the time series light intensity data.

An in situ inspection system and method to inspect a honeycomb body skin in a skinning system. The inspection system includes a line illuminator to generate a line illumination on the skin perpendicular to an axial direction of the honeycomb body travel, and a detector to detect the line illumination scattered from the skin and generate a signal based on the detected line illumination. A controller is configured to receive the signal generated by the detector, compare the received signal to a previously stored defect free signal in real-time, and control at least one skinning process parameter based on the comparison. The method includes in situ inspecting the skin and controlling at least one skinning process parameter based on the inspection. In the method, the in situ inspection includes illuminating a line of the skin perpendicular to the axial direction and detecting the illuminated line scattered from the skin.
Abstract:
A surface scanning wafer inspection system with independently adjustable scan pitch and associated methods of operation are presented. The scan pitch may be adjusted independently from an illumination area on the surface of a wafer. In some embodiments, scan pitch is adjusted while the illumination area remains constant. For example, defect sensitivity is adjusted by adjusting the rate of translation of a wafer relative to the rate of rotation of the wafer without additional optical adjustments. In some examples, the scan pitch is adjusted to achieve a desired defect sensitivity over an entire wafer. In other examples, the scan pitch is adjusted during wafer inspection to optimize defect sensitivity and throughput. In other examples, the scan pitch is adjusted to maximize defect sensitivity within the damage limit of a wafer under inspection.

Abstract:
While an illumination optical system is irradiating the surface of a contaminated standard wafer with illumination light, this illumination light is scanned over the surface of the contaminated standard wafer, then detectors of a detection optical system each detect the light scattered from the surface of the contaminated standard wafer, next a predefined reference value in addition to detection results on the scattered light is used to calculate a compensation parameter “Comp” for detection sensitivity correction of photomultiplier tubes of the detectors, and the compensation parameter “Comp” is separated into a time-varying deterioration parameter “P”, an optical characteristics parameter “Opt”, and a sensor characteristics parameter “Lr”, and correspondingly managed. This makes is easy to calibrate the detection sensitivity.
Abstract:
In an examining apparatus or method, values of thickness and characteristic of an object, or distributions thereof can be simultaneously acquired. The examining apparatus includes a portion 9 for irradiating an object 2 with radiation, a portion 10 for detecting the radiation from the object, an acquiring portion 26, a storing portion 21 and a calculating portion 20. The acquiring portion acquires transmission time associated with detection time of radiation, and amplitude of the radiation. The storing portion beforehand stores relationship data between the transmission time and amplitude, and representative values of characteristic of the object. The calculating portion obtains values of thickness and characteristic of the object based on the transmission time, amplitude and relationship data.
