Claim 6:
7. The apparatus for trapping of a reaction by-product with an extended available collection area of claim 1, wherein the lower end trapping unit (33) is connected to the lower portion of the intermediate trapping unit (32) and includes an outer periphery trapping plate part (331) and an inner trapping plate part (332) which have a plurality of gas holes formed on surfaces thereof and are disposed in multiple stages,
wherein the lower end trapping unit (33) prevents the gas, which is subjected to the trapping reaction in the inner region and the outer region of the intermediate trapping unit (32), from flowing downward directly into the gas discharge port (13a) provided on a lower plate of the housing and the gas is guided toward an inner side from the outer periphery, such that the trapping reaction is finally performed, and then the gas flows into the upper side of the gas discharge port (13a) protruding upward from the central portion of the lower plate of the housing and then flows downward.
