Publication number: 20110308464Abstract: Processing gas is supplied from the central upper part of a processing chamber to a wafer on a mounting board, while the processing chamber is exhausted from processing gas exhaust passages at areas outside of the wafer. In addition, purge gas is supplied from purge gas supply passages to a buffer chamber formed between the peripheral part of a container main body and that of a cover body. The supplied flow-rate of the processing gas is made less than the exhaust flow-rate in the processing gas exhaust passages. Accordingly, the purge gas in the buffer chamber is drawn into the processing chamber via a purge gas supply hole formed of a gap between the container main body and the cover body due to a negative pressure inside the processing chamber caused by a difference between the flow rates.Type: ApplicationFiled: August 26, 2011Publication date: December 22, 2011Applicant: TOKYO ELECTRON LIMITEDInventors: Hiroyuki KUDOH, Hideto Mori, Shinji Okada, Toyohisa Tsuruda
