Abstract:
1. A gas introduction structure that is reciprocatingly movable in a predetermined direction, comprising: a processing gas introduction system configured to introduce a processing gas into a processing chamber in which a substrate is subjected to a predetermined processing under a clean atmosphere; and a processing gas supply line connected to the processing gas introduction system and to an external processing gas supply source to supply the processing gas from the processing gas supply source to the processing gas introduction system, wherein mutual relative positions of the processing gas supply source and the processing gas introduction system are configured to be changed, wherein the processing gas supply line includes: a first bendable portion connected to the processing gas supply source; a second bendable portion connected to the processing gas introduction system; and a non-bendable pipe interposed between the first bendable portion and the second bendable portion, and wherein an inclined angle of the non-bendable pipe is changed with bending of the first bendable portion or the second bendable portion.
