Non-contact optical thickness measurement. Applicable even for thickness measurements of semiconductor wafers where high precision is required.
The new product "CHRocodile 2LR ver2" is a device that can non-contact measure the thickness of materials such as wafers and coatings. It adopts a new detector different from the previous "CHRocodile 2LR," allowing for approximately twice the thickness measurement range and more precise measurements. It can also be applied inline, and the CHRocodile 2LR has a proven track record with many customers. It is capable of measuring the thickness of semiconductor wafers like Si, as well as films, resins, glass, and solar cells. It supports interference film thickness of up to 16 layers. 【Features】 ■ Wide thickness measurement range, compatible with various materials With a rich lineup of probes, it covers thicknesses from thin films (around 32μm) to thick films (3900μm). (The high-precision measurement range is 16~1900μm with linearity of 0.35μm) ■ High resolution (sub-micron, minimum 1nm) ■ 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.
