    摘要： An inspection system for inspecting a surface of a wafer/mask/reticle can include a modular array. The modular array can include a plurality of time delay integration (TDI) sensor modules, each TDI sensor module having a TDI sensor and a plurality of localized circuits for driving and processing the TDI sensor. At least one of the localized circuits can control a clock associated with the TDI sensor. At least one light pipe can be used to distribute a source illumination to the plurality of TDI sensor modules. The plurality of TDI sensor modules can be positioned capture a same inspection region or different inspection regions. The plurality of TDI sensor modules can be identical or provide for different integration stages. Spacing of the modules can be arranged to provide 100% coverage of the inspection region in one pass or for fractional coverage requiring two or more passes for complete coverage.

    摘要： Inspection of EUV patterned masks, blank masks, and patterned wafers generated by EUV patterned masks requires high magnification and a large field of view at the image plane. An EUV inspection system can include a light source directed to an inspected surface, a detector for detecting light deflected from the inspected surface, and an optic configuration for directing the light from the inspected surface to the detector. In particular, the detector can include a plurality of sensor modules. Additionally, the optic configuration can include a plurality of mirrors that provide magnification of at least 100× within an optical path less than 5 meters long. In one embodiment, the optical path is approximately 2-3 meters long.

    摘要： A method and apparatus for simultaneous high-speed inspection and acquisition of multiple data channels is provided. The method and apparatus enables inspecting semiconductor wafers and reticles and comprises converting a single image region into two image sections, reorienting one image into a transposed configuration enabling simultaneous scanning of two inspected object locations with a single sensor, and controlling acquisition parameters for a second image by using information collected from a first image in a feedback arrangement. The design provides a dual-linear or time-delay-integration sensor operating in a split readout configuration mode to simultaneously provide data from two regions of the sensor using two sets of readout circuitry.

    摘要： Disclosed is a method and apparatus for using far field scattered and diffracted light to determine whether a collection of topological features on a surface (e.g., a semiconductor wafer) conforms to an expected condition or quality. This determination is made by comparing the far field diffraction pattern of a surface under consideration with a corresponding diffraction pattern (a "baseline"). If the baseline diffraction pattern and far field diffraction pattern varies by more than a prescribed amount or in characteristic ways, it is inferred that the surface features are defective. The method may be implemented as a die-to-die comparison of far field diffraction patterns of two dies on a semiconductor wafer. The portion of the far field scattered and diffracted light sensitive to a relevant condition or quality can also be reimaged to obtain an improved signal-to-noise ratio.

    摘要： An improved inspection system using back-side illuminated linear sensing for propagating charge through a sensor is provided. Focusing optics may be used with a back side illuminated linear sensor to inspect specimens, the back side illuminated linear sensor operating to advance an accumulated charge from one side of each pixel to the other side. The design comprises controlling voltage profiles across pixel gates from one side to the other side in order to advance charge between to a charge accumulation region. Controlling voltage profiles comprises attaching a continuous polysilicon gate across each pixel within a back side illuminated linear sensor array. Polysilicon gates and voltages applied thereto enable efficient electron advancement using a controlled voltage profile.
