SILICON MATERIALS AND SILICON WAFER PURITY ANALYSIS SERVICE

The main raw material of solar cells is silicon, just like semiconductor silicon wafers, which are divided into monocrystalline silicon, polycrystalline silicon and amorphous silicon. Especially high-purity silicon material.

SGS provides testing services for polysilicon chunks, wafers, blue tape/dies, and silica powder.

• Silicon crystal raw material purity analysis (ICP-MS method)
• Silicon crystal raw material purity analysis (GD-MS method)
• Analysis of trace carbon (C) and oxygen (O) content in silicon crystal raw materials
• Analysis of trace impure metal elements in silicon crystal raw materials
• Wafer surface roughness analysis
• Analysis of impurities on the wafer surface (ball method)
• Surface impedance value
• Silicon crystal material and silicon wafer purity inspection service
