Used TOPCON Vi-4202 #293617669 for sale

TOPCON Vi-4202 is a powerful automated mask and wafer inspection equipment. It is designed to enable fast and accurate detection of defects in masks and wafers throughout the fabrication process. The system is capable of high-resolution inspection of both patterned areas and non-patterned areas on lithographic masks and wafers without requiring any specific skills or training. The machine is designed to inspect both positive and negative masks, and it offers users an unprecedented level of control over their quality control process. Vi-4202 features an advanced optical unit which enables the machine to capture data from masks and wafers with an ultra-high resolution of up to 100 nm. The machine uses an articulating structure which allows it to move freely and capture data from any area of the mask or wafer. It also features a fully automated multi-point calibration tool, which ensures that the data is always of the highest quality. This asset is also equipped with advanced software, which allows users to automate routine tasks such as defect location and characterization. The model also offers a variety of imaging and measurement tools. It uses a novel multiple illumination equipment which allows it to measure both the lithographic mask pattern and non-patterned areas of a wafer. This system also includes a unique image correction unit that adjusts the image focus, contrast, and brightness of the images to optimize the inspection results. The machine includes a plethora of other features, such as pattern matching and alignment, defect location, defect classification, defect review, data storage, reporting, and error-checking capabilities. This allows users to perform rapid and precise defect detection, analysis, and sorting, thus enabling a high level of quality control. In addition, TOPCON Vi-4202's software offers advanced graphical aids that allow users to view fault-data from the machine in 3-dimensional patterns. This feature allows users to better visualize and identify defect patterns quickly. Overall, Vi-4202 is a powerful and versatile mask and wafer inspection tool. Its features enable it to provide rapid, accurate, and comprehensive inspection of masks and wafers, making it an invaluable tool for quality control in the fabrication of lithographic masks.
