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.

Inspection of Sub Surface Structures on Si and other wafer materials

Optical Contrast Enhancement: Recipe Selectable Band-Pass, Long-Pass Filters provide a tunable solution for optimized imaging performance

Digital Contrast Enhancement: Recipe Control of Contrast w/ Histogram

Advanced Infrared Imaging Technology:

     Standard: Visible Though NIR (400-1050nm)

     Optional: SWIR (900nm-1700nm)

     Optional: High-Resolution Options

Automated & Programmable Illumination, Wavelength Selection, Aperture Diaphragm, and Camera Exposure / Gain ensures best Image Contrast
