SUBSTRATE PROCESSING APPARATUS AND SUBSTRATE PROCESSING METHOD

摘要

Provided is a substrate processing apparatus. The substrate processing apparatus includes a lower chamber having an opened upper side, an upper chamber opening or closing the upper side of the lower chamber, the upper chamber defining an inner space, in which a process is performed on a substrate, together with the lower chamber, a showerhead disposed on a lower portion of the upper chamber to supply a reaction gas toward the inner space, wherein a buffer space is defined between the showerhead and the upper chamber, a partition member disposed in the buffer space to partition the buffer space into a plurality of diffusion regions, and a plurality of gas supply ports disposed in the upper chamber to supply the reaction gas toward each of the diffusion regions.
