Measurement of wafer thickness

Measurement of a gap from connecting rod bearing

It measures the thickness of the siliconwafer prepared by slicing silicon ingot thinly.

The sensor detects the gap between the upper and lower level base plates to calculate the wafer thickness. 05 type sensors are mainly used, but also 09 type sensors are also occasionally used.
The sensor are embedded into the upper base plate.
