Used AMAT / APPLIED MATERIALS 0020-20112 #9361625 for sale

AMAT / APPLIED MATERIALS 0020-20112 is a mask and wafer inspection equipment designed for applications in semiconductor manufacturing. The system integrates advanced optics, image processing, and automation technology to provide complete mask to wafer comparison analysis for both photolithographic process and defect reviews. This unit is considered to be among the most productive and reliable mask and wafer inspection systems in its class. The machine contains a high-resolution monochrome CCD camera, which provides a magnification accuracy of up to 2X, and is capable of providing both top-down and side-view images. The camera includes several features which enable precise alignment of the two images, and can spot defects as small as 1μm. The wafer stage has a large range of motion (an X-Y travel range of up to 30mm) and a sub-micron level of accuracy, which allows for accurate auto-centring of the wafer before scanning. Furthermore, the tool features enhanced light shielding and optimized illumination techniques, for improved image contrast and noise immunity. The asset also includes several automated image processing functions for analysis of CCD images. Tools such as Adaptive Thresholding, Edge Detection, Local Contrast Enhancement, Fourier Transformation, Grain Size Analysis and Segmentation are provided to enable features such as defect detection and classification, colour analysis and metrology. These tools are further optimized to improve accuracy and speed in the inspection process. In addition, the model incorporates a graphical user interface (GUI), which provides an intuitive working environment for the user. The GUI consists of simple menus and toolbars which allow users to control the setup, image processing and analysis procedure. Additionally, the GUI also provides visualization tools such as histograms and 3D graphs, which allow users to better analyze and interpret the image data. Overall, AMAT 0020-20112 is an advanced and feature-rich mask and wafer inspection equipment which provides unparalleled image analysis capabilities and automation for semiconductor wafer fabrication processes. It simplifies and accelerates the arduous inspection process, providing essential insights and improvements to the manufacturing process.
