Abstract: To manufacture a semiconductor device, a structure is formed by alternately stacking a plurality of first films and a plurality of second films one-by-one on a substrate. A vertical hole is formed to vertically pass through the structure. A carbon-containing barrier film is formed to conformally cover an inner sidewall of the vertical hole. The carbon-containing barrier film is in contact with portions of the plurality of first films and the plurality of second films. A sacrificial metal film is formed on the carbon-containing barrier film in the vertical hole. The sacrificial metal film is removed to expose the carbon-containing barrier film. The carbon-containing barrier film is removed using an ashing process.
