Method for determining surface contamination of polycrystalline silicon |
| abstract |
The invention relates to a method for determining a surface contamination of polycrystalline silicon, comprising the steps a) providing two polycrystalline silicon rods by deposition in a Siemens reactor; b) impurities in the first of the two bars are determined immediately after deposition; c) The second rod is passed through one or more equipment in which polycrystalline silicon rods are further processed into rod pieces or polysilicon fragments, optionally cleaned, stored or packaged; d) Then impurities in the second bar are determined; wherein the difference of the particular impurities in the first and second bars results in surface contamination of polycrystalline silicon due to equipment and plant environment. |
