Abstract
Described herein is a technique capable of removing by-products before the by-products are deposited to an exhaust part. According to one aspect of the technique, there is provided a method of manufacturing a semiconductor device including: (a) processing a substrate while maintaining an inner pressure of a process chamber at a process pressure by adjusting a valve configured to adjust the inner pressure of the process chamber; (b) changing the inner pressure of the process chamber from the process pressure to an atmospheric pressure; and (c) supplying a predetermined gas to a downstream side of the valve to bypass the process chamber while performing (b).
