Detector for concentration of additive
专利汇可以提供Detector for concentration of additive专利检索，专利查询，专利分析的服务。并且PURPOSE: To accurately measure and control the concn. of an additive by calculating the correspondent relation of both the amount of electricity in a stripping peak of an electroplating bath having the known concn. of the additive and the concn. of the additive and calculating the concn. from the above-mentioned relation in the unknown concn. of the additive.
CONSTITUTION: A cyclic voltammetry method is applied to an electroplating bath having the known concn. of an additive. The correspondent rela-tion of both the concn. of the additive and the amount of electricity in a stripping peak is previously stored in a memory part. Then the amount of electricity in the stripping peak of the electroplating bath having the unknown concn. of the additive is calculated. The concn. of the additive in the electroplating bath is calculated on the basis of this amount of electricity from the data of the stored corres-pondent relation.
