Abstract

The present disclosure relates to an apparatus for collecting by-products for a semiconductor manufacturing process with improved collection space efficiency, and an object of the present disclosure is to provide an apparatus for collecting by-products, which provides a multi-stage collection function while guiding a flow of exhaust gas through an internal collection tower, which includes an upper-end collection part, an intermediate collection part, and a lower-end collection part by guiding the exhaust gas to a lower side through a peripheral portion after heating the exhaust gas, which is introduced into the collection apparatus, by using a heater, and allows main by-products to be accumulated in an internal space of the intermediate collection part having open gas flow structures of an inner region and an inner wall housing, thereby improving efficiency of a collection space.
