Substrate processing device
First Claim
1. A substrate processing apparatus, comprising:
- a reaction container which accommodates a substrate, to which a plurality of reaction gases are supplied, and which forms a space where said substrate is subjected to desired processing, an exhaust port which is opened in said reaction container for exhausting gas from said reaction container, and a gas supply system for supplying at least the plurality of reaction gases to said reaction container, wherein said gas supply system comprises;
a cleaning gas supply unit for supplying cleaning gas which removes accretion adhering to an inner side of said reaction container by subjecting said substrate to the desired processing, a post-processing gas supply unit for supplying post-processing gas which can remove an element included in the cleaning gas remaining in said reaction container after the accretion is removed by supplying the cleaning gas, and said post-processing gas includes all reaction gases used when said substrate is subjected to the desired processing.

Abstract
A substrate processing device comprises a reaction vessel 11 forming a space receiving a substrate 1 and adapted to have a plurality of reaction gases supplied thereto to perform desired processing of the substrate, an exhaust port 16 formed in the reaction vessel 11 for exhausting the reaction vessel 11, and a gas supply system 70A, 70B for supplying at least a plurality of reaction gases into the reaction vessel 11, the gas supply system 70A, 70B including a cleaning gas supply unit for supplying a cleaning gas to perform desired processing of the substrate 1 to thereby remove adherents in the reaction vessel 11, and a post-processing gas supply unit for supplying a post-processing gas capable of removing the elements contained in the cleaning gas remaining in the reaction vessel 11 after the adherents have been removed by supplying the cleaning gas, the post-processing gas containing all of the reaction gases used in performing desired processing of the substrate.

8. A substrate processing apparatus which supplies a plurality of reaction gases alternately and forms a thin film on a substrate, comprising:
-
a reaction container, a plurality of exclusive supply nozzles for respectively and exclusively supplying the plurality of the reaction gases, and a control apparatus for controlling the substrate processing apparatus such that cleaning gas is supplied from one of the supply nozzles into said reaction container at the time of cleaning, all reaction gases used for processing a substrate are alternately supplied into said reaction container from the exclusive supply nozzles after the cleaning gas is supplied and before the substrate is processed. - View Dependent Claims (9, 10)
