Abstract:
1. A processing apparatus for performing a specified processing on a target object, comprising: an evacuable processing vessel made of metal; a mounting table, provided within the processing vessel, including a mounting surface for mounting the target object thereon; a heating unit for heating the target object; and a gas introduction unit for introducing a processing gas into the processing vessel, wherein a sidewall of the processing vessel comprises a plurality of interconnected block bodies adjoined via a plurality of seal members to form inter-block heat insulating vacuum layers between the adjoining block bodies, wherein the interconnected block bodies include: an upper block body supporting a ceiling plate of the processing vessel; a middle block body supporting a gas injection portion that injects the processing gas into the processing vessel, the gas injection portion serving as a part of the gas introduction unit; and a lower block body corresponding in position to the mounting table, wherein the inter-block heat insulating vacuum layers include a first heat insulating vacuum layer between the upper block body and the middle block body and a second heat insulating vacuum layer between the middle block body and the lower block body, wherein the first heat insulating vacuum layer and the second heat insulating vacuum layer communicate with each other through a common gas exhaust line which is formed in the interconnected block bodies and which is connected to a vacuum exhaust system, and wherein the mounting surface is disposed at a location that, in a vertical direction, is between an upper face of the lower block body and a lower face of the lower block body; and the adjoining block bodies are arranged to adjoin to each other in the vertical direction, wherein the inter-block heat insulating vacuum layers are defined by the block bodies adjoining each other in the vertical direction and by seal members, which hermetically seal inner and outer peripheral sides of inter-block gaps provided between the adjoining block bodies.
