METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE

摘要

Provided is a method of manufacturing a semiconductor device wherein a cleaning process on the inside of an exhaust buffer chamber may be performed sufficiently and satisfactorily even if gases are exhausted using the exhaust buffer chamber. The method includes: (a) processing a substrate placed on a substrate placing surface in a processing space by supplying gases onto the substrate in the processing space through a side facing the substrate placing surface while exhausting the gases from the processing space using an exhaust buffer chamber including a space surrounding an outer circumference of a side portion of the processing space; and (b) cleaning and inside of the exhaust buffer chamber by supplying a cleaning gas into the exhaust buffer chamber through a cleaning gas supply pipe communicating with the space of the exhaust buffer chamber.
