Optical sensor for measuring a wide range of thickness from 0.5 to 200 um. High-speed sampling at 5 kHz. Ideal for monitoring applications during processing.
Non-contact optical thickness measurement. Applicable for thickness measurement of semiconductor wafers where high precision is required. The new product 'CHRocodile 2 SX' is a device that can measure the thickness of materials such as wafers and coatings without contact. It supports high-speed sampling of up to 5 kHz, making it suitable for inline applications. In addition to measuring the thickness of semiconductor wafers like Si, it can also measure the thickness of films, resins, glass, solar cells, and more. In particular, when thickness monitoring is desired during wafer grinding, it can measure thicknesses from 200 µm to 0.5 µm for Si wafers. 【Features】 ■ Wide range of thickness measurement, compatible with various materials With a rich lineup of probes, it can measure thicknesses from thin films (around 2 µm) to thick films (1000 µm) at optical lengths, and from 0.5 to 200 µm for Si. ■ High resolution (sub-micron, minimum 3 nm @ optical length) ■ Contributes to reducing development costs and shortening development lead times, with a software development kit (DLL, etc.) available for device integration ■ Extensive track record in the semiconductor industry *For more details, please refer to the documentation.
