Used HITACHI IS 2500 #293703871 for sale

HITACHI IS 2500 is an advanced mask and wafer inspection equipment designed to accurately identify flaws and defects in the manufacturing of semiconductor components. This system can rapidly carry out detailed 2D and 3D topographical inspections, allowing for the detection of defects that are otherwise difficult to locate. HITACHI IS-2500 utilizes advanced inspection technology, including a proprietary algorithm, to accurately identify defects such as cracks, scratches, and surface imperfections which could be caused by anything from environmental damages to production defects. This unit can analyze wafers with diameters ranging from 150mm to 200mm. The advanced optical machine in IS 2500 makes use of brightfield illumination, combined with two high-resolution CCD cameras, to acquire a detailed image of the surface of the wafer. This tool then applies the proprietary algorithm to compare the acquired image to a predetermined image, allowing for the detection of even the smallest of defects. User-friendly software, combined with a user-friendly graphical interface, allows for easy setup and operation of the asset. It also offers various analysis tools for understanding the surface of the wafer, including maps of both the 3D wafer surface and the 2D surface defect. Additionally, it offers a variety of statistical evaluation tools designed to make interpretation of results easier and more accurate. The model also has a few more advanced features, including comparison between different wafers and automated location for defects, as well as automated pattern recognition and analysis. All of this make IS-2500 one of the most advanced mask and wafer inspection systems currently available.
