摘要： In a process for the manufacture of a semiconductor integrated circuit device having an inlaid interconnect structure by embedding a conductor film in a recess, such as a trench or hole, formed in an organic insulating film which constitutes an interlevel dielectric film and includes an organosiloxane as a main component, the recess, such as a trench or hole, is formed by subjecting the organic insulating film to plasma dry etching in a CF-based gas/N2/Ar gas in order to suppress the formation of an abnormal shape on the bottom of the recess, upon formation of a photoresist film over the organic insulating film, followed by formation of the recess therein with the photoresist film as an etching mask.
