An apparatus for removing harmful components in a semiconductor exhaust gas includes: a first water scrubber for washing with water a gas to be processed; a gas decomposer tower disposed downstream of the first water scrubber; a second water scrubber disposed downstream of the gas decomposer tower; and a burner tower disposed downstream of the second water scrubber for burning the processed gas, wherein the gas decomposer tower is capable of thermally decomposing a mixture gas of a saturated or unsaturated hydrocarbon gas and a perfluorocarbon or a perfluoride compound by maintaining the mixture gas at a temperature of 600 DEG C. or more in the absence of separated O2.
