Abstract:
1. A computer-readable medium containing software that, when executed by a controller, causes a semiconductor substrate processing system to clean a chamber after process a substrate, using a method comprising: providing said substrate to said chamber, said chamber having a first portion comprising a substrate support pedestal, a second portion comprising a lid having a source of radio-frequency power, and a blocking plate electrode and a gas distribution plate electrode defining a first volume, wherein the gas distribution plate electrode is electrically isolated from the first portion and is disposed between the first portion and the lid, and the gas distribution plate electrode and the substrate support pedestal defining a second volume; grounding the substrate pedestal through a switch in a first position while supplying a processing gas into the chamber and second volume, applying a radio-frequency power from said source to the second portion, energizing the processing gas to a plasma in the second volume and performing a plasma enhanced chemical vapor deposition process in the second volume; removing the substrate from the processing chamber; grounding the gas distribution plate electrode through a switch in a second position while supplying a cleaning gas into the chamber and the first volume, applying radio-frequency power from said source to the lid and blocking plate electrode, and energizing the cleaning gas to a plasma in the first volume.
