Abstract

PROBLEM TO BE SOLVED: To allow end point detection of processing and periodical cleaning with a high efficiency and high reliability with no damage to performance of semiconductor processing by supplying moisture-containing gas inside a reaction chamber for performing chemical reaction of moisture contained in gas with a deposit inside the reaction chamber. SOLUTION: A semiconductor processing equipment has a gas line and one purge line 10, and a flow control valve 11 and a hydrogeneous gas supply device 12 are connected to the purge line 10. The hydrogeneous gas supply device 12 produces and supplys hydrogeneous gas where, for instance, about one % of a moisture content is added to inactive gas such as air or nitrogen gas, argon gas and this hydrogeneous gas, of which flow is controlled by the flow control valve 11, is supplied inside a reaction chamber 1. Since the reaction chamber 1 is supplied with a moisture-containing gas, moisture contained in the gas chemically reacts with a deposit deposited on the inner wall surface of the reaction chamber 1 and on the electrode surface, and the deposit is decomposed and removed by this chemical reaction.
