Used NIKON Optistation #9218871 for sale

NIKON Optistation is a comprehensive and versatile mask and wafer inspection equipment used in semiconductor manufacturing. It uses advanced imaging technology, specialized optics, and artificial intelligence algorithms to inspect various types of masks and wafer surfaces. Optistation combines a high resolution imaging system with high accuracy and repeatability to detect the presence of even the smallest defects. NIKON Optistation utilizes an advanced imaging unit, consisting of a digital camera, light source and image capture optics. The digital camera captures an image of the mask or wafer surface, and then transfers it to a connected host machine for processing. The light source reflects off of the mask or wafer surface, and creates an image that is captured by the image capture optics. Optistation is capable of inspecting for both primary and secondary defects. Primary defects are inspectable by the tool's computational imaging algorithms, while secondary defects require a more sophisticated analysis that takes into account the shape, size and orientation of each defect. The asset can also be used to inspect bare and passivated surfaces, and is capable of detecting a variety of masking problems, such as bridging, pinholes, and exposed dielectric material. The powerful AI algorithms NIKON Optistation uses can recognize both localized and entire masking shapes, such as circles, rectangles, and squares. Optistation also includes a high precision positioning model, which allows for fast and repeatable measurements in the X, Y and Z directions. This ensure that the image captured by the equipment is precisely aligned with the mask or wafer surface. Additionally, NIKON Optistation offers several features that enhance defect detection and usability. The system includes an integrated microscope, which allows the user to zoom in and view defects in greater detail. Additionally, Optistation comes with a digital image processing module, which can detect minor changes in the images over time. Overall, NIKON Optistation is an advanced mask and wafer inspection unit that offers precision, accuracy, and repeatability. By leveraging advanced imaging technology, specialized optics and artificial intelligence algorithms, Optistation provides an effective means to detect and analyze defects on masks and wafers.
