Wafer sorter thickness, line mark, warpage measurement module

The thickness of the silicon sorter is measured by three pairs of optical displacement sensors. One pair of sensors is placed above the silicon wafer and one is placed under the silicon wafer. The silicon to be tested passes through the middle of the pair of sensors. Therefore, the 3-line thickness value of the silicon wafer is finally obtained. The thickness of the silicon sorter is measured by three pairs of optical displacement sensors. One pair of sensors is placed above the silicon wafer and one is placed under the silicon wafer. The silicon to be tested passes through the middle of the pair of sensors. Therefore, the 3-line thickness value of the silicon wafer is finally obtained. Various morphological indicators such as the signal of each pair of sensors, the thickness of the sample, and the line marks can be calculated. d=A-(x1+x2) d: Wafer thickness x1, x2: Distance from sensor to wafer surface A: Correction constant (distance between sensor pairs) The structure of the test module is as follows: China Hardware Business Network The measurement structure is as follows. Three measuring probes are used up and down, and a total of six measuring probes are used. China Hardware Business Network The depth information measured by each probe is as follows: China Hardware Business Network The above picture shows the depth information map after zeroing. Note that there is a small spike near 130mm, which represents the depth expansion of this, that is, there is a line mark. Both thickness and warpage can be calculated from the appropriate data model based on the six graph data.
