AST-MEMS Automated
Automated MEMS Inspection System
The Automated MEMS Inspection System provides advanced imaging capabilities for microelectromechanical systems, delivering exceptional subsurface visualization and precise metrology. With both Near-Infrared (NIR) and Short-Wave Infrared (SWIR) imaging technologies, this system penetrates silicon and other wafer materials to inspect hidden structures, measure critical dimensions, and verify alignment in complex multi-layer MEMS devices.
Product Highlights
The automated MEMS Inspection system integrates specialized infrared imaging technology with high-precision motion control to examine subsurface features that are invisible to conventional optical inspection methods. The system captures detailed images through full-thickness wafers, making it ideal for inspecting bonded wafers, 3D stacked structures, and other complex MEMS configurations.
