Used KLA / TENCOR / PROMETRIX 6420 Surfscan #9254029 for sale

KLA / TENCOR / PROMETRIX 6420 Surfscan is a wafer testing and metrology equipment designed for semiconductor manufacturing. It is specifically designed for inspecting and analyzing the defectivity of advanced lithography processes, as well as for measuring and quantifying the parameters of the surface of a wafer. The Surfscan 6420 is composed of a fully automated wafer handling system, a high-resolution imaging unit, and a patented beam-shift technology that allows for high-resolution imaging. The machine is capable of performing non-contact optical inspections up to 45 mm, and can also measure and quantify surface parameters on any size wafer up to 300 mm. The tool further features advanced software that can reliably find defects of various sizes, as well as automated measurement routines that deliver repeatable and reliable data. The asset uses high-resolution imaging to detect defects, such as particulate, scratches, and printing anomalies, that would otherwise be hard to find using traditional test methods. Images are then analyzed through an automated image processing model that compares the images to allowable templates and tolerances. The equipment also includes a Software Development Kit for users to create custom measurement and analysis applications. In addition to its defect-detection capabilities, the Surfscan 6420 features pattern overlay and optimized contouring tools. This allows it to precisely measure a wide variety of parameters, including line-edge roughness, step height, width, and sidewall angle. The system's automated software detection algorithms can measure these parameters over an entire wafer or across individual die, and then quantify the results in easy-to-read graphs. Overall, KLA 6420 Surfscan is a powerful and advanced wafer testing and metrology unit. It is designed to meet the most stringent industry standards, providing precision and accuracy in the detection and measurement of semiconductor defects. With its fully automated processes, easy-to-use software, and high-resolution imaging, the Surfscan 6420 is an invaluable tool for semiconductor manufacturers.
