Used KLA / TENCOR 6420 Surfscan #293742067 for sale

KLA / TENCOR 6420 Wafer Testing and Metrology equipment is a multi-functional set of software and hardware-based platforms that allow automated inspection of semiconductor wafers. This allows manufacturers to ensure the quality and integrity of their products during manufacturing and to improve overall yield rates. KLA 6420 system consists of several elements that are tasked with ensuring quality control. The unit includes a 4D 3001 Wafer Measurement Station, which uses X plasma inspection to identify sub-dimensional defects and contaminants. This station also provides wafer pattern alignment for creating overlay measurements to report any misalignment issues. The machine also includes a 4D 3001 Inspection Station which uses Near-Field Scanning Optical Microscopy (NSOM) to inspect the topography of the wafer. This station has eight internally-controlled illumination modes and multiple sensors to help with identifying defects. The 4D 3101 Mapping Tool uses macro defect review to evaluate wafers for contamination that can cause asset failure. The CDS 3001 Wafer Cleaning Model uses particle bombardment technology to clean wafers of particles. The Cleaner Checkstation uses a four-point measurement program to check contamination levels before, during, and after the wafer cleaning process. In addition to the software and hardware-based platforms, TENCOR 6420 also utilizes Quality Manager software. Quality Manager is a process control tool that allows manufacturers to create, implement, and monitor manufacturing processes. This software enables users to reduce variability and increase wafer functionality. Overall, 6420 is a comprehensive equipment that provides a complete solution for testing and metrology in the semiconductor manufacturing industry. It enables users to create quality control protocols, measure and analyze wafers, and clean wafers to reduce contamination. With the help of this system, manufacturers can improve product yield, reduce cost and time to produce, and increase profitability.
