Nanospec 6100 Thin Film Analyzer

The NanoSpec 6100 thin film thickness measurement system utilizes non-contact spectroscopic reflectometry to measure sites as small as 25 m in diameter on reflecting substrates. The tool measures film thicknesses in the range of 200 20 m with the visible light source and 25 20 m with the UV light source. Substrates up to 200 mm in diameter can be measured on the system. It uses a computerized sample stage and an auto focus system to rapidly generate 2D and 3D film thickness uniformity maps and statistics. These features are very useful for optimizing the uniformity of thin film deposition and etch processes. The tool is also capable of measuring multiple layers if the optical constants of the materials are known.
