Protects a method and apparatus for measuring thin-film thickness on textured silicon substrates — supporting TDM's optical metrology used in PV and semiconductor film inspection.
Covers offline laboratory equipment, inline production line integration, and two in-situ monitoring routes. SE31 and SE310 monitor film thickness and reflectance from the coating head. SE31-FM provides a separate wide-band transmission/reflection optical-film monitoring route; specifications are model-specific.
Versatile for PV, semiconductor, display panels, optical coatings, and new energy. Supports multi-layer composite films, metal/dielectric/ITO layer detection.
Published systems cover optical film thickness, reflectance, transmittance, n/k, band gap, PL, mapping and 3D profiling. Measurement range, repeatability and sampling mode are specified by model.
Complete set of services including equipment, line integration, software, on-site calibration, and lifetime after-sales technical support.
