  • Abstract
    This article reports novel copper seed layers containing dilute Ru or RuNx for the barrierless metallization. Based on XRD, FIB, TEM, resistivity and leakage current measurement results, we conclude that copper does not react with Si up to 680°C for 1 hour when the Ru-or RuNx-bearing seed layer is directly in contact with the barrier-free Si. Our results shed lights on the possibility of using these layers in the barrierless metallization process.
