  • Abstract
    In this paper, we introduce the composition of SNC solution and clarify the principles why SNC solution can be used to realize the in-line analysis of noble metallic impurities on the silicon wafer surface. We also show several recoveries of noble metals by analyzing the intentionally contaminated wafers.
