Used TOPCON WM 3 #9236040 for sale

TOPCON WM 3 is a fully automated mask and wafer inspection equipment. It is capable of inspecting both masks and wafers with high accuracy by means of a wide range of advanced optical inspection technologies. The system has a field-of-view of up to 250mm and can detect a variety of defects, including those related to registration, exposed patterns, foreign objects, surface contaminants, particles, streaks, and scratches. The unit also offers a comprehensive suite of fault detection tools for both single wafer and multiple wafer products. The machine utilizes advanced scan-based imaging, which enables it to rapidly acquire large fields of view, as well as to detect even the smallest process abnormalities. The tool also offers optional sample preparation capabilities such as planarization and watermarking, which ensures that it can reliably detect even the most challenging defects. The mask and wafer inspection asset is user friendly and includes an intuitive graphical user interface (GUI) and context-sensitive help. The GUI allows for quick navigation between features and tasks, as well as various settings which can be adjusted to the operator's preference. The model also provides a range of productivity-enhancing features such as automatic defect tolerancing, automatic defect masking, multi-feature defect localisation, and optional defect classification. The equipment provides a highly reliable and repeatable inspection process due to its patented dual-arm design. The system arms enable it to automatically track defect locations and determine if they are acceptable or not. This improves throughput and eliminates potential human error associated with manual defect removal. The dual-arm design also provides step-and-repeat capabilities for multiple wafer inspection operations, which leads to further improvements in process repeatability and throughput. TOPCON WM-3 is a comprehensive solution for both mask and wafer inspection, and provides excellent value for money. Its advanced features, intuitive user interface, and robust design make it an ideal choice for any production environment.
