The "CHRocodile 2 IT sensor" can measure the thickness of wafers during work processing.

In the semiconductor industry, it is necessary to measure the physical thickness of wafers at multiple manufacturing stages, such as CMP and mechanical grinding. To monitor and optimize the entire process, it is important to have a grasp of the thickness; however, this task is currently mainly performed using mechanical contact probes. These probes have significant drawbacks, including the need for contact with the wafer, surface damage, and reference values for thickness measurement from the chuck table, and they also wear out, necessitating frequent replacements. Our "CHRocodile 2 IT sensor" can measure the thickness of wafers during processing using non-contact, non-destructive optical measurement technology. 【Features】 - Optical sensor provides more accurate results than conventional contact measurement devices. - Direct feedback improves the reproducibility of wafer thickness from several micrometers to less than 0.5 micrometers. - High-speed measurement and non-contact passive probes allow for the acquisition of a large amount of thickness data across the entire wafer area simply by moving the probe over the sample. - Variability in wafer thickness is revealed from the results, enabling the management of variability during the grinding process. *Product details can be viewed in the materials available for download in PDF format.
