Classification: CPC H  C | IPC B  H

Claim 8:
9. A by-product collection apparatus which collects a by-product generated during a manufacturing process of manufacturing a semiconductor, the apparatus comprising:
a by-product collection module connected to a pipeline in series and configured to collect a by-product from a by-product gas, wherein the by-product gas flows in the pipeline having an inlet pipe and an outlet pipe provided at upper and lower portions of a first casing;
a cooling water supply module including a cooling water tank and a cooling water pump in a second casing and configured to supply and recover cooling water to and from the by-product collection module through a cooling pipe;
a water tank which is installed below the second casing of the cooling water supply module and is a place in which the cooling water leaking from an inside of the second casing is collected; and
a leak detection sensor installed on a bottom surface of the water tank and configured to detect the leaked cooling water,
wherein leakage of the cooling water is detected with only a small amount of water leakage.
