摘要:
The method comprises the step of forming an interconnection trench 38 in an inter-layer insulation film 34, the step of forming an interconnection layer 44 of Cu as the main material in the interconnection trench 38, and the step of performing nitrogen-two-fluid processing of concurrently spraying pure water with ammonia and hydrogen solved in and nitrogen gas on the surface of the interconnection layer 44 buried in the interconnection trench 38.
