Thin Film Metrology

Effective quality assurance is the key to achieving high quality while ensuring cost-effective production. This is especially true in industries that utilize thin films and coatings, where variations in coating thickness or uniformity can lead not only to product quality failure, but also to increased cost through ineffective use of raw materials.

The ETA concept

We supply the measurement excellence needed for true quality assurance. Fast measurements and stable optical geometries guarantee accurate, comprehensive process feedback. The mainstream ETA spectral measurement products presented here are the ETA-SST and ETA-CSS for laboratory applications, and the ETA-TCM for comprehensive inline quality assurance. Together, or separately, they provide developers and manufacturers with comprehensive measurement tools for a range of applications:

SOLAR CELLS

By using industry-proven spectrometer technology and proprietary algorithms, AudioDev’s range of ETA testers for the solar business can help you optimize your production process in regards to silicon.nitride coatings on wafer-based solar cells. The new Helios-range measures key characteristics such as the layer thickness, color and refractive index of Silicon Nitride layer, both in-line and offline.

FLAT PANEL DISPLAYS

ETA systems help you control production quality and stability. For color filter production for example, chromaticity and layer thickness are key parameters to monitor. Using ETA-TCM inline measurement, coating homogeneity is monitored sheet after sheet. This ensures that potential coater problems are detected immediately, allowing direct countermeasures by the operator.
Result: yield increase and better insight into weak links in your production chain.

TECHNICAL GLASS & PRECISION OPTICS

Do you want to bring your coating processes to perfection? ETA systems will give you detailed insight into the quality of anti-reflective coatings, full- as well as semi-reflectors and filters. A variety of systems for reflectance and transmittance measurements are available for inline and offline use.

With the ETA-ARC-AT, fast and accurate non-destructive testing of coated curved surfaces enables 100% of quality assurance.

PLASTICS

If you produce plastic foils for packaging materials and electronic applications, stable product quality is guaranteed by full inline monitoring with ETA-TCM, to control the thickness, transmittance or color of the materials. ETA systems are available for foil thickness measurement from extremely thin to very thick.

PACKAGING

To be cost-effective and profitable, plastic foil production for the very competitive packaging industry must achieve maximum process output and minimum raw material waste – while delivering uniform product and coating thickness. With ETA-TCM inline monitoring and control, you can achieve all these objectives simultaneously.

PAINT

Manufacturers can save enormous quantities of paint and varnish with detailed knowledge of their coating process. Never spend a drop of paint too much anymore! Any paint or varnish on metal or plastic can be measured – either in the laboratory or inline.
