Claim 0:
1. A method, comprising:
providing a deposition or cleaning apparatus with a reaction chamber inside an outer chamber forming a double chamber structure, the reaction chamber having a processing position and a lowered position;
providing a substrate holder; and
moving the reaction chamber vertically between the processing position and the lowered position by an exhaust line comprising a bellows connected between the reaction chamber and the outer chamber, the lowered position being for loading one or more substrates onto the substrate holder at a substrate loading level, and the exhaust line being positioned below the reaction chamber,
wherein the reaction chamber moves below the substrate loading level at the loading position to above both the substrate loading level and above the substrate holder at the processing position,
wherein a length of the bellows of the exhaust line changes when the reaction chamber is moved vertically, and
wherein the exhaust line has gastight sidewalls and allows fluid from the reaction chamber to pass through the exhaust line.
