An etching method includes: providing, within a chamber, a substrate that includes at least a silicon-containing material and a molybdenum film or a tungsten film which is in an exposed state, and selectively etching the molybdenum film or the tungsten film relative to the silicon-containing material by supplying, into the chamber, an oxidation gas and a hexafluoride gas as an etching gas.

Etching method and etching apparatus

A predetermined process is performed on two target substrates using a substrate processing device that includes two processing parts for performing a substrate process on each of the two target substrates, a gas supply mechanism for separately supplying gases to the two processing parts, and a common exhaust mechanism for collectively exhausting the gases inside the two processing parts. A first mode is executed in which an HF gas and an NHgas are supplied to one of the two processing parts, and the HF gas is not supplied to the other of the two processing parts. Subsequently, a second mode is executed in which the HF gas and the NHgas are supplied to the two processing parts under the same gas conditions. In the first mode, a pressure difference is prevented from occurring between the two processing parts.

Substrate processing method and substrate processing device

An etching method includes: providing, in a chamber, a substrate including a structure including a first film selected from a molybdenum film and a tungsten film; performing a first etching on the first film by supplying an oxidation gas and a first gas selected from a MoFgas and a WFgas into the chamber; when a pore present inside the first film is exposed by the first etching, filling the pore with one of molybdenum and tungsten by stopping the first etching and supplying a reduction gas and a second gas selected the MoFgas and the WFgas into the chamber; and performing a second etching on a filling layer formed in the filling and the first film by supplying the oxidation gas and a third gas selected from the MoFgas and the WFgas into the chamber.

There is provided an etching method, including: loading a substrate having a metallic film formed on the substrate into a processing container; and subsequently, oxidizing and etching the metallic film by setting an internal pressure of the processing container to a pressure higher than 2.40&#xd7;10Pa and supplying an oxidizing gas for oxidizing the metallic film and an etching gas comprising &#x3b2;-diketone into the processing container.

There is provided an etching method including: a step of disposing a substrate in a chamber, the substrate having a silicon nitride film, a silicon oxide film, a silicon, and a silicon germanium; a step of setting a pressure in the chamber to 1,333 Pa or more; and a step of selectively etching the silicon nitride film with respect to the silicon oxide film, the silicon, and the silicon germanium by supplying a hydrogen fluoride gas into the chamber.

Substrate processing apparatus, substrate processing method and storage medium

There is disclosed a substrate processing method for etching a substrate on which a first and a second silicon oxide layer having different film qualities are formed side by side. The substrate processing method includes: a first etching step of supplying a halogen-containing gas that is not activated to the substrate and sublimating reaction by-products generated by reaction between the halogen-containing gas and the first and the second silicon oxide layer; and a second etching step of etching the substrate by radicals generated by activating the halogen-containing gas.
