Novel methods, systems, and apparatuses for reclaiming annealing gases from a high pressure annealing processing system are disclosed. According to an embodiment, the exhaust gasses from the high pressure annealing processing system are directed into a gas reclaiming system only when a precious gas, e.g., deuterium is used. The annealing gas is the separated from other gasses used in the high pressure annealing processing system and is then pressurized, filtered, and purified prior to transferring the gas to a bulk storage distribution unit. In one embodiment, the reclaimed gas is then again provided to the high pressure annealing processing system to anneal the wafers.
