1. A system for providing support to a deposition reactor to prevent thermal stress fracture, the system comprising:
- a horizontally oriented platform positioned below and coupled to the deposition reactor, wherein a top portion of the deposition rector is attached to an external frame at an attachment point;
an attachment mechanism positioned below the horizontally oriented platform and attached to the external frame;
at least one gas bellows positioned between the platform and the attachment mechanism; and
a pressure regulating mechanism coupled to the gas bellows and configured to automatically regulate gas pressure inside the gas bellows to move the platform to allow the attachment point of the top portion of the deposition reactor to remain at a same position while the deposition reactor expands or contracts due to temperature changes.

6. A deposition tool, comprising:
-
an external frame; a reactor that includes a chamber, a top gas delivery mechanism positioned above and coupled to a top portion of the chamber, and a bottom gas delivery mechanism positioned below and coupled to the chamber, wherein the top gas delivery mechanism is attached to the external frame at an attachment point; and a support system coupling together the external frame and the reactor, wherein the support system comprises; a horizontally oriented platform positioned below the bottom gas delivery system, thereby providing support to the reactor; an attachment mechanism attached to the external frame; at least one gas bellows positioned between the platform and the attachment mechanism; and a pressure regulating mechanism coupled to the gas bellows and configured to automatically regulate gas pressure inside the gas bellows to move the platform to allow the attachment point to remain at a same position while the chamber expands or contracts due to temperature changes. - View Dependent Claims (7, 8, 9, 10, 11)
