Abstract:
A dry processing apparatus comprising:holding means for holding a substrate to be processed in a chamber; supply means for supplying a process gas into the chamber; exhaustion means for exhausting the chamber through an exhaustion outlet formed in the chamber; and a baffle plate for partitioning an inside of the chamber into a processing space in which the supply means is provided and an exhaustion space which is closer to the exhaustion outlet than the processing space, wherein the baffle plate includes opening portions which are formed such that an opening area of each of the opening portions which are located on a processing-space side is greater than an opening area of said each opening portion which is located on an exhaustion-space side, and at least a part of said each opening portion is constituted by a side wall inclined with respect to a surface of the opening portion which is located on the processing space side or the exhaustion-space side.
