Abstract
A substrate processing apparatus includes a chamber body having an upper opening, a chamber lid part having a lower opening, and a shield plate arranged in a lid internal space of the chamber lid part. The radial dimension of the shield plate is greater than that of the lower opening. Covering the upper opening of the chamber body with the chamber lid part forms a chamber that internally houses a substrate. In the substrate processing apparatus, before the substrate is conveyed and the chamber is formed, the lid internal space of the chamber lid part is filled with the gas supplied from a gas supply part, in a state in which the shield plate overlaps with the lower opening. This allows the chamber to be quickly filled with the gas to achieve a desired low oxygen atmosphere after the formation of the chamber.
