Used KLA / TENCOR 6420 Surfscan #293767201 for sale

KLA / TENCOR 6420 is an industry-leading wafer testing and metrology equipment designed to deliver rapid and accurate measurement of semiconductor device features. This system combines advanced optics, digital imaging, and touchscreen technology to provide users with a comprehensive platform for wafer testing and analysis. KLA 6420's robust optics enable the capture of high-resolution images of wafer surface features, along with supporting measurement and failure analysis. A wafer can be measured to tolerances of +/-2um (micrometers) or better, providing operators with superior data in determining device performance. TENCOR 6420's user interface is based on a 19" touchscreen display that offers an intuitive, menu-driven unit for the operation of the machine. In addition to standard controls, the tool also features customizable user menus and a drag-and-drop image comparison feature. With its powerful onboard imaging, 6420 allows users to detect sub-micrometer defects on the wafer surface and facilitate repairs accordingly. The unit includes both a high power zoom and a high resolution capable of imaging wafers with linear resolutions of 2um/pixel or less. For advanced analysis of specific device features, KLA / TENCOR 6420 also integrates an automated image comparison feature. This critical feature allows for the direct comparison of images for subtle changes or measurement of critical dimensions, giving operators a higher degree of accuracy. This image comparison feature also enables users to easily review the progress of device fabrication over the life of a production run and identify any significant changes that could affect performance. For wafer testing and metrology operations, KLA 6420 includes an integrated particle analysis package, which allows operators to detect and quantify contaminants on wafers with unobtrusive accuracy. This powerful feature provides detailed and accurate particle data, which can be used to verify process cleanliness, control fablot yield, and monitor product quality. In addition, TENCOR 6420 comes with a wide range of options and accessories, including an automated wafer stage and automated vision systems. The wafer stage allows for automatic wafer loading, positioning and orientation, while the vision asset can be used to inspect the surface features of a wafer in real-time. 6420 provides a comprehensive platform for advanced wafer testing and metrology, offering users cutting-edge image analysis and particle measurement capabilities. With its intuitive user interface, high resolution imaging, and groundbreaking metrology tools, KLA / TENCOR 6420 provides users with a powerful tool for advanced wafer testing and measurement.
