In one exemplary embodiment, a substrate processing method is provided. This substrate processing method comprises the steps of: providing a substrate including a metal compound film and a mask defining an opening on the metal compound film to a plasma processing chamber; and etching the metal compound film by forming a plasma from a first processing gas including a boron- and halogen-containing gas and a hydrogen-containing gas.

Substrate processing method and substrate processing apparatus

An etching method includes forming a film on a surface of a substrate having a region to be etched and a mask. The mask is provided on the region and includes an opening that partially exposes the region. The film is made of the same material as that of the region. The etching method further includes etching the region.

Etching method, substrate processing apparatus, and substrate processing system

A substrate processing method includes forming a pre-coat film on an in-chamber part disposed in a chamber, and subsequently processing one or more substrates. The forming a pre-coat film includes forming a first film on the in-chamber part without using plasma or by using a first plasma generated under a condition that sputtering is suppressed on the in-chamber part, and forming a second film on a surface of the first film by using a second plasma.

Substrate processing method

An etching method includes (a) performing a plasma etching on an organic film, having a mask formed thereon, to form a recess in the organic film; (b) forming an organic protective film on a side wall surface of the recess in the organic film; and (c) performing an additional plasma etching on the organic film after (b).
