Used KOKUSAI VR-30A #293643665 for sale

KOKUSAI VR-30A is an advanced wafer testing and metrology equipment that can analyze and process semiconductor wafers. It is used to measure and inspect wafers for defects during their production process. The system is equipped with a high-speed die-to-die measurement device for wafers of various sizes, as well as a die aligner for more precise inspection and then microdefect inspection. VR-30A has a high-resolution color image sensor that can detect defects on a wide range of wafer sizes from mm to cm range. The unit is also equipped with a two-dimensional precision stage that can provide high-accuracy alignment with minimal backlash. KOKUSAI VR-30A employs advanced image processing algorithms to detect and analyze defects in wafers. The machine can detect scratch, chip, line, and granular defects. Moreover, it can automatically correct and enhance images while detecting defects. It can also identify defects on different parts of a single wafer in real-time. VR-30A tool uses automated 3D metrology technology to accurately measure wafers and can also measure wafer surfaces. The asset uses dual-beam laser interferometry to accurately and quickly measure wafer flatness and depth. It has a multi-coordinate measurement capability that can measure up to three wafers simultaneously. Additionally, the machine is also equipped with a patented multiple beam profile focus measuring model that can accurately measure a wide range of heights from the surface to the back of the wafer. KOKUSAI VR-30A equipment can also measure other parameters such as surface reflectance, surface uniformity, grain size, and surface deposit. Furthermore, the device employs automated calibration and verification to ensure accurate measurement results. VR-30A wafer testing and metrology system is an advanced and reliable unit that can be used in many wafer production processes. It is designed to detect and analyze defects quickly and accurately, while also providing precision metrology measurements. This machine is highly reliable and efficient and should provide users with great results.
