The Talysurf CCI SunStar coherence correlation interferometer is designed for photovoltaic and semiconductor applications. It can measure film thickness from 5 μm to less than 300 nm while obtaining information regarding interface roughness, pinhole defects, and delamination of coated surfaces. A 4 Mpixel camera provides imaging, with a closed-loop Z scanning mechanism.

TAYLOR HOBSON LAUNCHES TALYSURF CCI SUNSTAR
World-Leading Non-Contact Measurement Capability
Joins Advanced Thin and Thick Film Analysis Technology
WEST CHICAGO, IL— Taylor Hobson, a global leader in ultra-precision measurement instrumentation, has introduced the Talysurf CCI SunStar coherence correlation interferometer that merges world-leading non-contact dimensional measurement capability with advanced thin and thick film analysis technology. The CCI SunStar was developed to specifically meet the requirements of the most demanding photovoltaic and semiconductor applications.
The CCI SunStar seamlessly integrates the latest thin-film analysis technology with dimensional and roughness measurement and analysis tools making it possible to measure film thickness from 5µm down to 300nm or less. From a single measurement, the CCI SunStar is able to obtain information on film thickness, interface roughness, pinhole defects and de-lamination of thin-coated surfaces. Among its unique features are a four-million-pixel camera for high-resolution imaging over a large area, auto-range and auto-fringe-find for ease of use, single mode of operation over all scan ranges, and a stable and robust closed-loop Z scanning mechanism.
The CCI SunStar is particularly well suited for metrology tasks related to the design and manufacture of advanced photovoltaic solar cells, whether those cells are first-, second- or third- generation designs. It is ideal for measuring the depth of scribe lines and surface texture of crystalline silicon solar cells. With its ability to measure surface roughness and trench depth, the CCI SunStar makes process control both faster and more cost effective.
The CCi SunStar also is ideal for the study and development of new solar cell materials and structures used in second- and third-generation thin-film solar cells. The high z resolution of the SunStar’s coherence correlation interferometry technique is ideal for measuring film thicknesses greater than 1 to 2 µm but less than 20 µm.
For more difficult to measure thinner films, proprietary software allows the CCI SunStar to accurately measure thicknesses down to 300 nm or less, depending on the optical properties of the film. The solar cell substrates it can measure accurately include cadmium telluride (CdTe), copper gallium diselenide (CIGS), indium tin oxide (ITO) and titanium dioxide (TiO2).
