Abstract:
A system to generate multiple beam lines in an oblique angle multi-beam spot scanning wafer inspection system includes a beam scanning device configured to scan a beam of illumination, an objective lens oriented at an oblique angle relative to the surface of a sample and with an optical axis perpendicular to a first scanning direction on the sample, and one or more optical elements positioned between the objective lens and the beam scanning device. The one or more optical elements split the beam into two or more offset beams such that the two or more offset beams are separated in a least a second direction perpendicular to the first direction. The one or more optical elements further modify the phase characteristics of the two or more offset beams such that the two or more offset beams are simultaneously in focus on the sample during a scan.
Abstract:
Method has laser scanner for pixel-precise imaging of fluorescent samples having fluorescent dyes. The scanner has sample table, laser and first optical system providing laser beam for exciting the samples, scanner head with deflecting element for scanning sample, first lens, second optical system for forwarding emission beams triggered by the laser beam and deflected by first lens and deflecting element to a detector, position encoder emitting position signals indicating location of the scanner head, electronic element for filtering the detector signals with a time constant and an A/D converter for digitizing the filtered detector signals. The filtered detector signals and the position encoder signals are acquired independently, in parallel and continuously by a computer and are related to a common time base, the A/D conversion being carried out often so that each pixel of an image is always assigned more than one data point.
Abstract:
A multi-spot scanning technique using a spot array having a predetermined gap between spots can advantageously provide scalability to a large number of spots as well as the elimination of cross-talk between channels. The multi-spot scanning technique can select a number of spots for the spot array (1D or 2D), determine a separation between the spots to minimize crosstalk, and perform a scan on a wafer using the spot array and a full field of view (FOV). Performing the scan includes performing a plurality of scan line cycles, wherein each scan line cycle can fill in gaps left by previous scan line cycles. This “delay and fill” scan allows large spacing between spots, thereby eliminating cross-talk at the detector plane. In one embodiment, the scan is begun and ended outside a desired scan area on the wafer to ensure full scan coverage.

Abstract:
The invention provides a method and apparatus for non-destructive testing of bonded structures, such as laminated or composite materials. A beam of coherent light is directed successively onto each point of the object. The reflected beam creates a speckle pattern. The pattern is observed once while the object is stationary and once while the object is mechanically excited. If the point being observed is free of defects, the speckle pattern will be substantially unaffected by the vibration of the excited object. If the point is defective, vibration will blur the speckle pattern. The entire object is scanned, point by point, and the results of the comparison of the speckle patterns obtained for each point are stored and displayed. In another embodiment, the object is made to vibrate continuously, and the apparatus determines whether the speckle pattern is sharp or blurred, for each point being scanned. The sharpness of the speckle pattern can be inferred from the measured intensity of the speckle pattern, or it can be calculated directly by a suitable algorithm. In general, if the detector has a nonlinear response characteristic, the total intensity of the speckle pattern will be lower when the pattern is blurred, and higher when the pattern is sharp. A low intensity therefore indicates that the point on the object is defective. As in the first embodiment, the results of the analysis are stored in a computer memory and displayed on a video monitor.
