Abstract

Provided are an ozone gas heating mechanism, a substrate processing apparatus, and a substrate processing method that reduce variations in substrate temperature due to supply of ozone gas. An ozone gas heating mechanism according to one embodiment includes: a gas supply unit, which is installed in a processing container of a substrate processing apparatus, and capable of supplying ozone gas to a substrate; and a gas supply pipe, which is connected to the gas supply unit and capable of supplying the gas A supply unit supplies the ozone gas; and a pipe heating unit provided in the gas supply pipe for heating the ozone gas in the gas supply pipe.

Description

technical field [0001] The invention relates to an ozone gas heating mechanism, a substrate processing device and a substrate processing method. Background technique [0002] Conventionally, in semiconductor manufacturing processes, ozone (O 3 )gas. Ozone gas is an unstable gas, so it has the ability to decompose and become stable oxygen (O 2 ) properties of the gas. Ozone gas is gradually decomposed at room temperature, but when it exceeds 200° C., ozone gas decomposes in about 2 to 3 seconds. Therefore, when ozone gas is used as a process gas, generally, ozone gas is supplied to a process container at room temperature (ordinary temperature) without heating. [0003] In addition, in recent years, there is a tendency to supply a large flow rate of ozone gas to a processing container to perform processing. However, when a large flow rate of ozone gas is supplied to the processing chamber, the temperature of the substrate may drop to affect the properties of the formed ox...
