Claim 2:
3. The apparatus for trapping of a reaction by-product with an extended available collection area of claim 1, wherein the intermediate trapping unit (32) includes a plurality of planar cross-shaped vertical plates (321) coupled to a lower portion spaced apart from the upper end trapping unit (31) at a predetermined interval and disposed to have gaps at predetermined intervals and defining a periphery, and
an individual vertical plate (321a) constituting the planar cross-shaped vertical plates (321) is formed in a trapezoidal shape in which an area of the vertical plate facing inward is increased from the top to the bottom and configured to provide a trapping space in which an upper space in the inner region is larger than a lower space in the inner region of the intermediate trapping unit (32).
