A ruthenium raw gas feed pipe (4) and an oxygen-containing gas feed pipe (5) are merged with each other at a location upstream of a gas mixing chamber (6), so that the ruthenium raw gas and the gas containing oxygen atoms (e.g., oxygen (O2), ozone (O3), etc.) are mixed with each other prior to entering the gas mixing chamber (6).

Abstract: When films of Ru(C2H5C5H4)2 are formed on a substrate by means of a thermal CVD method, the films are also deposited on members around the substrate, resulting in the formation of particles on the substrate and hence a reduction in the manufacturing yield. Thus, it is necessary to clean the interior of the reaction chamber, but in a conventional cleaning process, a cleaning time is long and hence manufacturing efficiency is low, increasing manufacturing costs. To improve these, a method of manufacturing semiconductor devices according to the present invention includes: a deposition process for forming a film containing Ru on a substrate in a reaction chamber; and a cleaning process for supplying a ClF3 gas to the reaction chamber so as to remove films, which were deposited on an inner surface of the reaction chamber in the deposition process, through thermochemical reactions.
