  • Publication number: 20100188486
    Abstract: An inspection system for inspecting a semiconductor wafer. The inspection system comprises an illumination setup for supplying broadband illumination. The broadband illumination can be of different contrasts, for example brightfield and darkfield broadband illumination. The inspection system further comprises a first image capture device and a second image capture device, each configured for receiving broadband illumination to capture images of the semiconductor wafer while the semiconductor wafer is in motion. The system comprises a number of tube lenses for enabling collimation of the broadband illumination. The system also comprises a stabilizing mechanism and an objective lens assembly. The system further comprises a thin line illumination emitter and a third image capture device for receiving thin line illumination to thereby capture three-dimensional images of the semiconductor wafer.

  • Publication number: 20100188499
    Abstract: A method and a system for inspecting a wafer. The system comprises an optical inspection head, a wafer table, a wafer stack, a XY table and vibration isolators. The optical inspection head comprises a number of illuminators, image capture devices, objective lens and other optical components. The system and method enables capture of brightfield images, darkfield images, 3D profile images and review images. Captured images are converted into image signals and transmitted to a programmable controller for processing. Inspection is performed while the wafer is in motion. Captured images are compared with reference images for detecting defects on the wafer. An exemplary reference creation process for creating reference images and an exemplary image inspection process is also provided by the present invention. The reference image creation process is an automated process.

  • Patent number: 6654658
    Abstract: A system for conditioning a plurality of semiconductor leads of a semiconductor device is provided. The system includes an array of comb blades, where each comb blade terminates at a notch that allows the semiconductor leads to be moved laterally through the notch. A controller connected to the comb blades, such as through an intervening motor and comb blade support, causes the comb blades to move relative to the semiconductor device, such as by holding the semiconductor device stationary, so as to perform lateral and vertical conditioning of the semiconductor leads.
