Assignee: J-SOLUTION CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  C | IPC B  H

Claim 9:
10. 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; and
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,
wherein the by-product collection module includes:
a first casing including an inlet pipe and an outlet pipe connected to a pipeline, through which the by-product gas flows, in upper and lower portions of the first casing;
a filtering member installed inside the first casing in a state in which an upper end of the filtering member communicates with a lower end of the inlet pipe, and configured to filter some by-product particles contained in the by-product gas while a lower end of the filtering member is blocked but the flow of the by-product gas is allowed through a side surface of the filtering member;
an upper deposition panel and a lower deposition panel installed across an inside of the first casing at positions vertically spaced apart from each other and configured to deposit the by-product while coming into contact with the by-product gas introduced through the filtering member; and
an upper cooling pipe and a lower cooling pipe installed inside the upper deposition panel and the lower deposition panel and allowing the cooling water supplied from the cooling water supply module to pass therethrough.
