Overview
A Dektak Profilometer is a precision instrument used to measure surface profiles, roughness, and thin film thickness. It is widely used in industries like materials science and semiconductor fabrication for high-accuracy surface characterization.
How Does It Work?
The Dektak Profilometer works using a contact-based stylus method:
- Stylus Movement: A sharp tip traces the surface contours.
- Scanning: Captures vertical displacements with nanometer accuracy.
- Data Processing: Converts stylus movements into a detailed 2D or 3D profile.
Applications
Common applications of a Dektak Profilometer include:
- Semiconductors: Measuring film thickness and roughness on wafers.
- Thin Film Deposition: Ensuring uniformity and evaluating coating thickness.
- Microelectronics: Characterizing patterns in MEMS devices.
- Material Science: Studying the surface morphology of metals, ceramics, and polymers.
