Used WACCO AVIS-B-10 #293661612 for sale

WACCO AVIS-B-10 is a state-of-the-art mask and wafer inspection equipment that provides users with superior accuracy, reliability and speed. The system utilizes an optical imaging unit to detect and measure defects on wafers and masks including scratches, pinholes and dirt. The machine's innovative design allows for greater accuracy and repeatability when compared to conventional inspection methods such as scanners or human manual inspections. AVIS-B-10 features two main inspection modes: the homogeneous background mode and the heterogeneous background mode. The homogeneous background mode is used to inspect shallow defects that occur in similar areas on a wafer or mask. This mode works by analyzing diffracted light scattered from wafer or mask surfaces, and then creating a reference image which is compared to the image of the area being inspected. If any differences or defects are detected, the tool can immediately alert its user. The heterogeneous background mode is used to inspect deeper defects, or when the features of a wafer or mask are too complex for the homogeneous background mode. This mode works by analyzing optical images of the wafer or mask being inspected and then creates a reference image. The differences between the reference image and the actual image are then compared, and any defects detected are immediately flagged. WACCO AVIS-B-10 also features an automated defect classification asset. This model uses an advanced artificial intelligence algorithm to scan the reference image and compare it to a set of pre-defined criteria, allowing the equipment to quickly classify any defects as being either potential catastrophic defects or false alarms. The system can further classify the type of defect and provide a detailed description to the user, allowing them to better understand the defect's nature and how to address it. AVIS-B-10 also features a precision measurement unit. This machine utilizes a laser triangulation tool to precisely measure the magnitude of a defect's depth and length, allowing the user to more accurately assess the severity of the defect and how to address it. Overall, WACCO AVIS-B-10 offers users superior accuracy and speed when it comes to mask and wafer inspection. Its advanced asset is capable of efficiently detecting and classifying defects, allowing users to address them quickly and accurately.
