Product Features
【Non-Contact Measurement】As a true non-contact film thickness measurement instrument, it avoids damaging thin films, making it especially suitable for fragile or sensitive materials such as photoresists and biological coatings, meeting the non-destructive requirements of semiconductor film thickness detection.
【High Precision and Wide Range】Vertical resolution up to 0.02nm, thickness measurement range covers 1nm to 3mm, not only capable of ultra-thin film thickness measurement at the nanoscale, but also handling thicker coatings, making it a truly precision film thickness measurement system.
【Versatile Applications】Whether transparent, semi-transparent, or low absorption coefficient films, they can all be measured. Covers solid, liquid, and gaseous films, meeting diverse needs such as OLED film thickness measurement, optical coating thickness measurement, and polymer film thickness detection.
【Rapid Measurement】Once configured, thickness and optical constant results are obtained within 1 second, greatly improving film thickness measurement efficiency, making it a powerful assistant for rapid film thickness detection on production lines.
Measurement Principle
The F20 employs the principle of light reflection interference. Incident light reflects off the upper and lower surfaces of the thin film, and the two reflected beams interfere with each other to form an oscillating spectrum. By analyzing the oscillation frequency of the spectrum, the film thickness can be precisely calculated (the denser the oscillation, the thicker the film layer), while also deriving optical constants such as refractive index (n) and extinction coefficient (k) - this is the core technical foundation of optical film thickness measurement instruments.

Frequently Asked Questions (FAQ)
What is the measurement principle of the F20 film thickness gauge?
As an optical film thickness gauge, the F20 employs the light reflection interference principle for non-contact measurement. Incident light penetrates the film layer, reflects off both the upper and lower surfaces, and produces an interference spectrum. By analyzing the oscillation frequency of the spectrum, the film thickness and optical constants (n and k values) are calculated, with results available within 1 second - this is a typical optical film thickness measurement method.
What types of films can the F20 measure?
Essentially all smooth, semi-transparent, or low-absorption coefficient films can be measured using this film thickness measurement instrument, including semiconductor materials (SiNx, amorphous silicon), polymers (SU-8 photoresist, parylene), transparent conductive films (ITO), optical coatings (TiO2, DLC), etc. Solid, liquid, and gaseous films are all measurable, and both single-layer and multi-layer stacked films are equally applicable, perfectly covering all types of film thickness measurement needs.
What is the measurement accuracy of the F20?
The precision film thickness measurement system of the F20 series can achieve accuracy of 0.02nm (Ångström-level resolution), with accuracy of 1nm or 0.2% of the measured thickness (whichever is greater), and stability as high as 0.05nm. For ultra-thin film detection requirements in the semiconductor and microelectronics fields, such as nanoscale film thickness measurement, it is fully capable.
Is the F20 film thickness gauge complex to install? Does it require professional personnel?
Installation is very simple. Simply connect this non-contact film thickness measurement device via USB to a computer running Windows, connect the sample stage, and setup is complete within minutes. The accompanying FILMeasure software has an intuitive interface that requires no professional training to operate, making film thickness detection fast and easy.
