ASM WS 896 is a wafer stepper designed for production or research use. It is a fully integrated equipment that combines the most advanced optics, motion control, computer control, and support systems for a variety of semiconductor lithography applications. Optics and Illumination At the heart of ASM WS896 the is a state-of-the-art projection optics system with a numerical aperture (NA) of 0.45 which provides a high resolution and uniform image across the entire area of the wafer. The illumination is provided through an LED array and optical elements, configured for uniform exposure across the wafer. Motion Control WS 896 features a full range of motion control options, including: Stepping and scanning of the wafer; Wafer-stacking capabilities, allowing for multiple exposures without re-positioning; Wafer drift stabilization for improved accuracy; and additional enhancements such as column-based servo control and frictionless XYZ stages. With these advanced motion control options, WS896 can accurately and efficiently expose wafers in low-volume production as well as large-scale research projects. Computer Control ASM WS 896 is fully integrated with the most advanced computer control systems in the industry, allowing for easy and efficient programming and setup. The computer-controlled unit runs a wide range of software packages, from simple fabrication instructions to advanced exposure recipes. It can also run CAD and CAM programs, integrating with digital lithography software for streamlined design-to-productivity. Support Systems ASM WS896 also features multiple support systems, including a comprehensive manual and automated wafer testing machine. This support tool includes: exposure monitor functions to monitor the integrity of each exposure; validation functions to ensure the accuracy of the exposure; and a cleaning asset to keep the optics clean and dust-free. In conclusion, WS 896 is a highly advanced, fully integrated wafer stepper model ideal for production and research use. Thanks to its state-of-the-art optics and motion control, advanced computer control systems, and comprehensive support systems, WS896 provides a reliable and efficient solution for any semiconductor lithography application.
