1. A film-forming device based on atomic layer deposition, the film-forming device comprising:
a chamber having a horizontal central axis, capable of maintaining a vacuum, and movable along the horizontal central axis, the chamber including an inner chamber and an outer chamber that houses the inner chamber;
a workpiece holder that aligns and holds workpieces to be processed in multiple stages in the inner chamber; and
a heater that heats an inside of the chamber,
wherein the outer chamber includes a first outer lid removably connected to the outer chamber and defining a first outer chamber side wall, and a second outer lid removably connected to the outer chamber and defining a second outer chamber side wall opposite to the first outer lid along the horizontal central axis,
wherein the inner chamber includes a first inner lid removably connected to the inner chamber and defining a first inner chamber side wall, and a second inner lid removably connected to the inner chamber and defining a second inner chamber side wall opposite to the first inner lid along the horizontal central axis,
the workpiece holder has a first end and a second end opposite the first end, the first inner lid directly cantilever-supports the first end of the workpiece holder, and the second inner lid is not directly connected to the second end of the workpiece holder during deposition, and
the inner chamber and the outer chamber are separately moveable horizontally relative to the workpiece holder and the first inner lid when the first inner lid is directly cantilever-supporting the first end of the workpiece holder.
