摘要:
In a single-substrate type apparatus for processing a substrate, the apparatus includes a chamber, a bottom panel, a solution supplying part and a substrate holder. The chamber has an upper portion and a lower portion. The bottom panel is detachably connected to the lower portion. The solution supplying part is connected to the bottom panel to supply a processing solution to the substrate in the chamber. The substrate holder provides the substrate into the chamber, the substrate holder holding both side portions of the substrate such that the substrate is vertically arranged.
