Method of Manufacturing Semiconductor Device

摘要

A method of manufacturing a semiconductor device includes processing a substrate accommodated in a process container accommodated in a housing by supplying a process gas onto the substrate; and exhausting the process container using an exhaust system comprising a first exhaust pipe connected to the process container, the first exhaust pipe having circular or oval cross-section perpendicular to an exhausting direction thereof; and a second exhaust pipe connected to the first exhaust pipe, the second exhaust pipe having square or rectangular cross-section perpendicular to the exhausting direction, wherein at least a portion of the second exhaust pipe is disposed within the housing.
