Abstract
A batch-type vertical substrate processing apparatus includes a processing chamber into which a substrate holder configured to stack and hold a plurality of target substrates in a height direction is inserted; and a plurality of flanges formed to protrude from an inner wall of the processing chamber toward an internal space of the processing chamber along a planar direction and configured to divide the interior of the processing chamber into a plurality of processing subspaces along the height direction, wherein the flanges include insertion holes through which the substrate holder is inserted, and diameters of the insertion holes are small at an upper side of the processing chamber and become gradually larger toward a lower side of the processing chamber.
