Abstract:
A semiconductor manufacturing method, comprising:a first step of carrying a substrate into a preliminary chamber from an external part; a second step of continuously supplying and exhausting an inert gas to and from said preliminary chamber at least from a time before opening a first gate valve between said preliminary chamber and a transfer chamber, after the substrate is carried into said preliminary chamber, a third step of transferring said substrate to said transfer chamber from said preliminary chamber, in a state in which the inert gas is continuously supplied and exhausted to and from said preliminary chamber and said transfer chamber, after said first gate valve is opened; a fourth step of transferring said substrate to a process chamber from said transfer chamber in a state in which the inert gas is continuously supplied and exhausted to and from said transfer chamber and said process chamber, after a second gate valve between said transfer chamber and said process chamber is opened; and a fifth step of subjecting said substrate to predetermined processing in said process chamber.
