This helps improve understanding of material thickness, deposition uniformity, and measurement of variations during manufacturing stages.
Surface Quality Verification
Surface Quality Verification™ has been integrated into the thin-film measurement workflow, so that this imaging technology helps engineers visually verify measurement areas before spectral analysis begins.
The observations that can be detected include:
- Dust and fine particles.
- Fibers and hairs.
- Surface residue or droplets.
- Sample edges and mounting structures.
- Obstructions or impurities that may affect the measurement.
Documenting and analyzing these visual factors doubles the accuracy of the results and ensures a permanent visual record for every analysis point.
🚗 Broad Support for Semiconductor Manufacturing Materials
The TF-Micro system has the ability to measure a wide range of materials and thin films used in semiconductor manufacturing, as it supports:

- High-k dielectrics.
- Transparent conductive oxides.
- Polysilicon.
- Semiconductor compound materials.
- MEMS (microelectromechanical) devices.
- Silicon-based photonics technologies.
- Thin-film layers in research and development.
Available functions depend on the system configuration, with the possibility of manual measurements, automated mapping, image-based quality verification, or combining all of these techniques within a unified software environment.
🏭 The Design Philosophy: The Modular System and Keeping Pace with Industrial Evolution
StellarNet continues to follow a modular-instrument philosophy that allows laboratories and industrial workshops to build a customized system that meets their current thin-film measurement needs through TF-Micro.
