SWIR Imaging for Semiconductor Inspection and Electronics Analysis
Short-wave infrared (SWIR) imaging helps engineers inspect silicon wafers, packaged devices, MEMS structures, interconnects, and electronics assemblies when visible cameras cannot reveal enough information. Because silicon becomes increasingly transparent at SWIR wavelengths, a SWIR camera or SWIR microscope can support non-destructive inspection, failure analysis, process development, and advanced semiconductor research.
Pembroke Instruments helps research labs, failure analysis teams, and process engineers select SWIR cameras, SWIR microscope configurations, SWIR hyperspectral imaging systems, and related optics for semiconductor inspection.
SWIR microscopy can reveal semiconductor structures and features hidden to visible imaging.
Why SWIR Imaging Works for Semiconductor Inspection
Visible cameras are excellent for surface inspection, but they cannot see through silicon. SWIR imaging gives semiconductor engineers another inspection modality: one that can reveal internal structures, buried features, die attach issues, wafer defects, and packaging-related problems without cutting the sample apart.
Through-Silicon Imaging
Silicon is opaque in the visible spectrum but becomes more transmissive in the SWIR range. This allows SWIR cameras to inspect features beneath the surface of silicon wafers and devices.
Non-Destructive Failure Analysis
SWIR microscopy can help locate cracks, voids, alignment errors, and internal structures before destructive cross-sectioning or more expensive analysis methods are used.
Packaging and Interconnect Inspection
For advanced packaging, SWIR imaging can support inspection of bonded wafers, device stacks, MEMS structures, and packaged components where internal alignment matters.
Complementary to Thermal Imaging
SWIR reveals structural and optical information. Thermal microscopes reveal heat generation, current leakage, and powered-device behavior. Together, they help diagnose different classes of electronics problems.

SWIR inspection is most valuable when internal structure, silicon transparency, or wavelength-dependent contrast provides information that a standard visible camera cannot capture.
Wafer Cracks and Edge Damage
Identify cracks, chips, and subsurface defects that may not be obvious in visible-light inspection.
Voids and Bonding Defects
Support inspection of bonded wafers, die attach regions, and packaging interfaces where internal voids may affect reliability.
Alignment and Registration
View alignment features through silicon to help evaluate wafer bonding, stacked devices, MEMS assemblies, and package structures.
Interconnects and Wire Bonds
Inspect internal features in packaged devices and electronics assemblies where visible access is limited.
MEMS and Microstructures
Analyze microstructures and cavities where SWIR transparency can reveal features buried below the surface.
Material and Process Variation
Use SWIR contrast to investigate non-uniformities associated with process development, inspection, and research.
SWIR vs. Thermal Microscopy for Semiconductor and Electronics Analysis
SWIR and thermal microscopy answer different questions. SWIR is typically selected for through-silicon and structural inspection. Thermal microscopy is selected when the goal is to see heat patterns, current leakage, localized hotspots, and powered-device behavior.
