Abstract

Silicon nitride gate dielectric metal-nitride-semiconductor (MNS) having a Si ₃ N ₄ film grown at 400 °C by microwave-excited high-density plasma has been developed. We demonstrated the electric characteristics of the MNS capacitors with the Si ₃ N ₄ film grown by microwave-excited high-density plasma using krypton (Kr) gas. The MNS capacitors have larger TDDB lifetime and have lower leakage current capability compared with the MOS capacitors. The TDDB lifetime of the Kr/NH ₃ Si ₃ N ₄ is three times larger than that of the Ar/NH ₃ Si ₃ N ₄ . Furthermore the TDDB characteristics of Si ₃ N ₄ on (1 1 0)Si are same as those of Si ₃ N ₄ on (1 0 0)Si.
