    摘要: An image processing system for use in semiconductor wafer inspection comprises a multiplicity of self-contained image processors for independently performing image cross-correlation and defect detection. The system may also comprise an image normalization engine for performing image brightness and contrast normalization. The self-contained image processors and image normalization engine access image data from a memory array; the array is fed data from a multiplicity of imaging modules operating in parallel. The memory array is configured to allow simultaneous access for data input, normalization, and cross-correlation and defect detection. Multiple image processing systems can be configured in parallel as a single image processing computer, all sending defect data to a common display module.

    摘要: A detector optics system for collecting secondary electrons (SEs) and/or backscattered electrons (BSEs) in a multiple charged particle beam test system is disclosed. Aspects of the detector optics system include: the ability to image and/or electrically test a number of locations simultaneously across the full width of a large substrate with high throughput and uniform collection efficiency while avoiding crosstalk between signals generated by neighboring beams. In one embodiment, a linear array of N electron beams causes SEs to be emitted from the substrate, which are then collected by one or more linear arrays of ≧2N detectors. Each linear array is connected to a signal combiner circuit which dynamically determines which detectors are collecting SEs generated by each electron beam as it scans across the substrate surface and then combines the signals from these detectors to form N simultaneous output signals (one per charged particle beam) for each detector array.

    摘要: A flat panel display substrate (FPDS) testing system configured such that prior to testing, the FPDS is loaded into a pallet to prevent breakage, and to provide electrical connections to test pads on the FPDS. The system achieves high throughput by testing FPDSs using one or more charged particle beams simultaneously with the following operations: unloading of already-tested substrates, loading of substrates ready for testing, assembly of pallets, and alignment of electrical contactors to a large number of FPDS test pads. The system design eliminates a prior art X-Y stage, and all moving electrical connections to the FPDS during testing, reducing costs and improving reliability. In one embodiment, the FPDS testing system has three subsystems: a process chamber, loadlock assembly, and pallet elevator; in another embodiment, the functions of loadlock and pallet elevator are combined to reduce system footprint.

    摘要: Methods and apparatus for integrated, in-line metrology of solar cells involve three distinct inspection and testing operations, prior to string and module assembly. Two of the inspections are performed by image analysis using bright field illumination. The third inspection involves electroluminescence imaging, where luminescence in the solar cell is achieved by inducing a forward bias in the solar cell, and analyzing a resulting grayscale image for defects.

    摘要: Improvements for a photovoltaic module (PVM) include the use of a micro-embossed, reflective optical film located in areas of the PVM not covered by the solar cells. The optical film is configured to reflect light incident upon the PVM onto the solar cells and may be formed from a polymeric material. Further enhancements include the use of a compliant heat conducting polymeric film on back sides of the solar cells and a heat conductive polymeric film deposited on an aluminum foil to form a composite film, which effects heat transfer from the solar cell junctions and improves cell efficiency. A top glass with selective frequency and anti-reflective coatings may also be used. Further, improved interconnects for the solar cells eliminate sharp edges, helping to avoid any potential for encapsulant tearing or tab “push-through” and resultant shorting during lamination.
