ABSTRACT:
A filtering device and a filtering method and a semiconductor fabricating method thereof. The filtering device is used for filtering a gas had a first temperature. The filtering device includes a casing, a cooling mechanism and at least one adsorbing element. The casing has an input opening, an output opening and a cooling space. The gas enters the cooling space through the input opening and leaves the cooling space through the output opening. The cooling mechanism coupled to the casing is used for maintaining the cooling space at a second temperature that is lower than the first temperature. At least one adsorbing element is disposed inside the cooling space and has a plurality of surface-increasing elements arranged in a direction parallel. The plurality of surface-increasing elements arranged in the direction parallel to that the gas flows inside the cooling space for contacting the gas and adsorbing particles in the gas.
