20250207244. Film Formation Method (Tokyo Electron Limited)
FILM FORMATION METHOD AND FILM FORMATION DEVICE
Abstract: a film forming method includes (a) to (e) below. (a) a substrate having a first film and a second film in different regions of a surface of the substrate is prepared. (b) a self-assembled monolayer is selectively formed on a surface of the second film using an organic compound not containing fluorine. (c) after (b), a target film is formed on a surface of the first film while inhibiting the target film from being formed on the surface of the second film using the self-assembled monolayer. (d) after (c), a partial portion of the target film is fluorinated faster than a remaining portion of the target film using a fluorine-containing gas. (e) after (d), the partial portion of the target film is etched faster than the remaining portion of the target film using an etching gas. the partial portion of the target film is deposited on the self-assembled monolayer.
