  • Patent number: 10600683
    Abstract: For simplifying the dual-damascene formation steps of a multilevel Cu interconnect, a formation step of an antireflective film below a photoresist film is omitted. Described specifically, an interlayer insulating film is dry etched with a photoresist film formed thereover as a mask, and interconnect trenches are formed by terminating etching at the surface of a stopper film formed in the interlayer insulating film. The stopper film is made of an SiCN film having a low optical reflectance, thereby causing it to serve as an antireflective film when the photoresist film is exposed.
