Claim:
1. A processing apparatus that processes a substrate, the processing apparatus comprising: a substrate supporting unit that supports a substrate in a processing space in which the substrate is processed; a first partitioning member that includes a ceiling portion having an opening and partitions the processing space from an outer space; a second partitioning member that is attached to the first partitioning member so as to close the opening and partition the processing space from the outer space together with the first partitioning member; and a matching device attached to the first partitioning member and situated above the second partitioning member, wherein the first partitioning member has an attachment surface around the opening, the attachment surface facing a space which a lower surface of the ceiling portion faces, wherein the second partitioning member has a portion disposed underneath and facing the attachment surface from below the attachment surface, the second partitioning member being attached to the first partitioning member by attaching the portion of the second partitioning member from below to the attachment surface of the first partitioning member, and wherein the processing apparatus is configured so that the second partitioning member can be removed from the first partitioning member, without removing the matching device, by moving the second partitioning member toward the space.
