Accurate sheet resistance measurement is critical in ensuring the quality and reliability of thin film and semiconductor manufacturing processes. It plays a central role in monitoring film uniformity, verifying conductivity, and maintaining strict process control. Discover industry-leading Filmetrics R50 and R54 systems to provide fast, non-contact resistance analysis for a variety of conductive and semi-conductive films.
What is Sheet Resistance?
Sheet resistance is a key electrical property of thin films, expressing resistance in ohms per square (Ω/□). It plays a crucial role in evaluating materials used in electronics, photovoltaics, displays, and coatings. Measuring sheet resistance allows manufacturers to verify conductivity, uniformity, and film thickness—ensuring reliable performance and process consistency.
Advanced Measurement with Filmetrics R50 and R54
Filmetrics R50 and R54 offer exceptional speed, accuracy, and ease of use. These systems use a four-point probe or eddy current method to measure sheet resistance without damaging the film surface, offering high precision across a wide resistance range.
Key Benefits:
- Non-Destructive Testing: Preserve film integrity with non-invasive measurements
- Wide Resistance Range: From low-resistivity metals to high-resistivity transparent films
- Fast and Repeatable: Automated measurements with consistent results in seconds
- Versatile Sample Handling: Suitable for wafers, coated glass, and flexible substrates
The Filmetrics R50 is ideal for routine measurements and general-purpose applications, while the R54 offers extended functionality for high-throughput environments and advanced analysis.
