An abnormality detection method includes: supplying a gas controlled to a selected rate to a gas supply pipe via the gas pipe connected to the gas supply pipe, thereby introducing the gas into a reaction region of a processing container provided in a processing apparatus from a gas hole of the gas supply pipe; measuring a pressure inside the gas pipe by a pressure gauge attached to the gas pipe; and detecting an abnormality of at least one of the gas supply pipe and the gas pipe based on the pressure measured at the measuring.

Abnormality detection method and processing apparatus

A film deposition method includes depositing an amorphous silicon film in a substrate under a process condition. The process condition includes supplying SiHgas into a processing chamber in which the substrate is placed. The process condition includes setting a temperature in the processing chamber to be in a range of greater than or equal to 300° C. and less than or equal to 440° C. The process condition includes setting a pressure of the processing chamber to be in a range of greater than or equal to 10 Torr and less than or equal to 100 Torr.

Film deposition method and method for forming polycrystalline silicon film

A cleaning method according to an aspect of the present disclosure includes: supplying a halogen-containing gas that does not contain fluorine to an interior of a processing container that is capable of being exhausted via an exhaust pipe to perform a cleaning; and supplying a fluorine-containing gas to at least one of the interior of the processing container and an interior of the exhaust pipe to perform the cleaning after the supplying the halogen-containing gas to perform the cleaning.

Cleaning method and substrate processing apparatus

A method of crystallizing an amorphous silicon film includes depositing the amorphous silicon film on a seed layer formed over a substrate while heating the amorphous silicon film at a first temperature, and forming a crystal nucleus in an outer layer of the amorphous silicon film by causing migration of silicon in the outer layer by heating the amorphous silicon film at a second temperature higher than the first temperature.

Method of crystallizing amorphous silicon film and deposition apparatus

To provide a method of depositing a silicon film that can crystallize the silicon film at low temperature and in a short time, and also can deposit the silicon film with high flatness. A method of depositing a silicon film includes supplying a silicon-containing gas on a seed layer, depositing an amorphous silicon film on the seed layer, supplying chlorosilane gas to the amorphous silicon film, and crystallizing the amorphous silicon film while forming a chlorosilane cap layer on the amorphous silicon film.

Method of depositing silicon film and film deposition apparatus

There is provided a method of forming a silicon film, which includes: a film forming step of forming the silicon film on a base, the silicon film having a film thickness thicker than a desired film thickness; and an etching step of reducing the film thickness of the silicon film by supplying an etching gas containing bromine or iodine to the silicon film.

Silicon film forming method and substrate processing apparatus

There is provided a cleaning method of a substrate processing apparatus comprising cleaning an inside of an exhaust pipe through which a gas of an inside of a processing container is exhausted. The cleaning the inside of the exhaust pipe includes: removing a deposit on a downstream side of an opening/closing valve in the exhaust pipe by supplying a first exhaust pipe cleaning gas containing fluorine to the downstream side of the opening/closing valve in the exhaust pipe in a state in which the opening/closing valve provided in a middle of the exhaust pipe is closed; and removing a deposit on an upstream side of the opening/closing valve in the exhaust pipe by supplying a second exhaust pipe cleaning gas not containing fluorine as a gas constituent element to the inside of the processing container in a state in which the opening/closing valve is opened.
