Abstract:
1. A method for processing a substrate, comprising: delivering said substrate to be plasma-processed onto a holding mechanism in a process chamber; introducing a process gas into said process chamber while an inside of said process chamber is evacuated by a first exhaust port in said process chamber; plasma-processing said substrate; and introducing, after said substrate is plasma-processed, a cleaning gas into said process chamber while the inside of said process chamber is evacuated by a second exhaust port positioned lower than said first exhaust port in said process chamber, thereby cleaning the inside of said process chamber, wherein said holding mechanism is moved upward when said substrate is plasma-processed so that said first exhaust port is positioned higher than said holding mechanism, and moved downward when the inside of said process chamber is cleaned so that the second exhaust port is positioned lower than said holding mechanism.
