Used TOPCON WM-7S #9280870 for sale

TOPCON WM-7S is an accurate and reliable mask & wafer inspection equipment designed to detect and measure defects on semiconductor and photomask substrates. Utilizing high-resolution optics, the system offers operators superior imaging capabilities and review accuracy when inspecting for both mask and wafer defects. The heart of the unit is its advanced image processor, which enables a total inspection time of only 9 seconds. During this process, a split-field CCD camera captures 2 images of the mask or wafer surface to detect defects in two different directions. Additionally, a laser scanning machine allows for a wide field of view and rapid movement of the optics over the sample surface, further enhancing the speed and efficiency of the tool. The control console for TOPCON WM 7S also features numerous automated controls, from setting review parameters to integrating the asset with external measurement tools. This facilitates the capture of complex defect patterns, such as a variety of line-of-sight marks, chromatic aberrations, and cracks, among other defects. To get the most out of the model, WM-7S also offers a number of advanced functionality features, such as photo-inspection, stencil-mode detection, and defect grading. In terms of accuracy and sensitivity, the equipment is capable of detecting defects down to 0.15μm, making it suitable for use across a wide range of industry applications. Furthermore, the usability of the system is further enhanced with features such as an intuitive user interface, a comprehensive Windows-compatible software package, and built-in data management tools. WM 7S is an efficient and reliable mask & wafer inspection unit that is ideal for detecting and measuring a variety of types of defects on substrates. Precise imaging and automated controls ensure that users are provided with a superior machine tailored to their specific inspection requirements. Furthermore, the tool is designed with usability, speed and accuracy in mind, making it an ideal choice for any application or production environment.
