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.

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

Advanced Vision Tool Library for Executing Optimized OA Focus, Pattern Find, and Geometric Measurements

 

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.
