Used KLA / TENCOR WI-2250 #9379062 for sale

KLA / TENCOR WI-2250 is a mask & wafer inspection equipment designed for detailed inspection of microscopic defects. It utilizes high-powered lasers with precision optics to gain a macro-level view of the components. KLA WI-2250 consists of both an optical subsystem and a sample-handling subsystem, which work together to provide thorough and highly accurate defect detection. The optical subsystem of TENCOR WI-2250 is capable of inspecting wafers at multiple magnifications, allowing for accurate, deep and large area defect detection. The optical subsystem makes extensive use of powerful lasers. The laser is carefully focused to project a light beam of high intensity across the width of the sample surface. When the laser beam strikes part of the sample, it triggers specialized light sensors that can detect any difference between a defect in the sample and the uninterrupted sample surface. This way, small defects such as micro-cracks, pin-holes, particles or contaminants can be accurately detected. The sample-handling subsystem of WI-2250 is responsible for scanning and moving the sample in order to capture highly accurate microscope images of the surfaces. The sample-handling subsystem includes a high-resolution target system used to precisely locate and identify defect locations. This subsystem is also capable of automatically aligning the sample with the associated pattern so that any warping or misalignment between the two can be quickly identified. KLA / TENCOR WI-2250 provides unparalleled accuracy in the detection of defects. It is renowned for its ability to detect even the smallest of defects, allowing for superior quality control in semiconductor manufacturing. The unit's wide range of magnifications allows it to provide detailed images of the wafer's surface. Furthermore, KLA WI-2250's target machine helps to quickly and accurately pinpoint any defect locations within the sample. This all combines to provide a comprehensive and highly reliable mask & wafer inspection tool.
