Abstract

See full text

According to one embodiment, a method of manufacturing a semiconductor device includes forming a first line pattern comprising a first film above an underlying layer, depositing a second film on a sidewall and a top surface of the first line pattern of the first film, etching the second film to eliminate the second film on the top surface of the first line pattern of the first film and leave the second film on the sidewall of the first line pattern of the first film, and removing the first line pattern to form a second line pattern of the second film above the underlying layer. The depositing the second film, etching the second film, and removing the first line pattern are sequentially performed within the same plasma processing device.
