Abstract:
1. A processing apparatus for carrying out predetermined processing of a plurality of processing objects, comprising: a processing container structure having a bottom opening and including a processing container having a processing space for housing the processing objects and a cover container surrounding an exterior of the processing container, said processing container having a nozzle housing area on one side of the processing space and a slit-like exhaust port on the opposite side of the processing space from the nozzle housing area; a lid configured to close the bottom opening of the processing container structure; a support structure configured to support the processing objects and can be inserted into and withdrawn from the processing container structure; a gas introduction means including a gas nozzle housed in the nozzle housing area; an exhaust means including a plurality of exhaust systems for exhausting the atmosphere in the processing container structure; a heating device configured to heat the processing objects; and a control device configured to control the gas introduction means, the exhaust means and the heating device, wherein an exhaust space is formed on an outer side of the slit-like exhaust port and on an inner side of the cover container, wherein the plurality of exhaust systems comprise a first exhaust system provided at a bottom of the cover container and a second exhaust system provided at a top of the cover container, the first exhaust system provided with a first vacuum pump and the second exhaust system provided with a second vacuum pump, wherein a gas ejected from the gas nozzle flows toward the slit-like exhaust port into the exhaust space between the processing container and the cover container, and is discharged through at least one of the first exhaust system and the second exhaust system to an outside of the processing container structure, wherein the cover container surrounds an entirety of the exterior of the processing container in a circumferential direction and comprises a cylindrical portion and an exhaust space forming portion bulging outwardly in an arc from the cylindrical portion so as to form the exhaust space, wherein the exhaust space forming portion is formed along a side wall of the cover container at a position facing the slit-like exhaust port, and wherein the exhaust space forming portion extends from the first exhaust system to the second exhaust system and is in communication with the first exhaust system and the second exhaust system.
