摘要:
PROBLEM TO BE SOLVED: To provide a direct contact technique by which a barrier metal layer between a Cu based alloy wiring composed of pure Cu or Cu alloy and a semiconductor layer is eliminated, and the Cu based alloy wiring is directly and securely connected to the semiconductor layer within a wide range of process margin. SOLUTION: A wiring structure has the semiconductor layer and Cu based alloy film composed of pure Cu or Cu alloy on a substrate in their order from the substrate side, and includes a laminate structure of: a (N, C, F, O) layer containing at least a kind of element selected from a group comprising nitrogen, carbon, fluorine and oxygen, between the semiconductor layer and Cu based alloy film in their order from the substrate side; and a Cu-Si diffusion layer containing Cu and Si. Any of elements such as nitrogen, carbon, fluorine and oxygen composing the (N, C, F, O) layer is coupled to Si of the semiconductor layer. COPYRIGHT: (C)2011,JPO&INPIT
