Used ASML YieldStar #9399584 for sale

ASML YieldStar is a high-end, advanced wafer testing and metrology equipment that is used to measure wafer characteristics during various fabrication steps. It provides small, accurate measurements of a variety of wafer patterns and is used for critical analysis during the production process. Core components of the system include a top-of-the-line wafer microscope, a high-accuracy positioning unit, and advanced image processing software. The microscope utilizes off-axis, bright field and dark field illumination to provide detailed images of the wafer. The positioning machine is capable of precisely maintaining a given relative position in three-dimensional space. This allows measurements to be taken through multiple depths and cross sections. In order to test a wafer, YieldStar tool can be programmed to accurately scan the sample and measure a variety of features. These could include the critical dimension sizes of line widths, etch depths, and density levels. The asset can also be used to measure contact Overlap, continuity, and yield. It can detect surface defects, such as scratches and pits, and measure surface flatness. Additionally, it is able to detect slits, slots and cavities. Data collected from the wafer is fed back to the software for further analysis. The software then uses a variety of computational algorithms for feature size and shape analysis, statistical evaluation, and charting. Additionally, ASML YieldStar model is able to provide product trend analysis and defect detection capabilities. YieldStar is an invaluable tool in today's semiconductor fabs. Its combination of high-precision metrology and advanced image processing software makes it ideal for inspecting complex patterns and detecting small defects. This is essential for the production of ever-shrinking wafer dimensions and denser patterns used in modern semiconductor fabrication. By improving the quality and accuracy of production, ASML YieldStar equipment is an essential cogs in the present and future of chip making.
