Test method for silicon wafer surface gloss
1 Scope
This document describes a method for testing the surface gloss of silicon wafers using the light reflection method at 20°, 60° or 85° geometries.
This document is suitable for testing the surface gloss of silicon etched wafers, polished wafers, and epitaxial wafers. It is not suitable for testing silicon wafers with patterns on the surface.

3 Terms and definitions
The terms and definitions defined in GB/T 9754 and GB/T 14264 and the following apply to this document.
3.1
gloss gloss
For a specified light source and acceptance angle, the luminous flux reflected from the specular direction of an object is the same as the specular direction of black glass with a refractive index of 1.567.
The ratio of reflected light flux.
Note 1.In order to determine the scale of specular gloss, the gloss value is specified for polished black glass with a refractive index of 1.567 at geometric angles of 20°, 60° and 85°.
is 100.
Note 2.The evaluation of the glossiness of the back side of the double-sided silicon polished wafer is calculated based on the glossiness of the front side of the polished wafer.
4 Method Principles
Under the conditions of the specified incident angle and the specified beam, the incident light shines on the sample surface through the lens, and the light in the direction of the specular reflection angle is obtained.
Beam, at this time, the reflected light intensity is determined by the surface properties of the sample material. The receiver collects the sample reflected light and compares it with the standard surface reflected light intensity.
Calculate and finally obtain the surface gloss of the sample. The schematic diagram of the glossiness test light path is shown in Figure 1.
