AST-MEMS Workstation
MEMS Inspection Workstation
The MEMS Inspection Workstation provides advanced imaging capabilities for microelectromechanical systems, delivering exceptional inspection capabilities including subsurface visualization and high-precision metrology performance within an integrated ergonomic workstation platform. Visible, Near-Infrared (NIR), and Short-Wave Infrared (SWIR) imaging technologies provide the capability to image through silicon and other wafer materials to inspect hidden structures, measure critical dimensions, and verify alignment in complex MEMS devices.
Product Highlights
The MEMS workstation integrates specialized infrared imaging technology with high-precision motion control to examine subsurface features that are invisible to conventional optical inspection methods. This integrated workstation captures detailed images for executing critical dimensional measurements and confirming overlay alignment patterns between wafer layers making it ideal for inspecting bonded structures and analyzing complex MEMS configurations.
