Abstract:
A substrate processing apparatus comprising:a substrate processing portion at which a plurality of substrates are treated by a process; a substrate waiting portion at which the substrates stand by for the process, the waiting portion being arranged below the processing portion; and a substrate lifter including a substrate supporting member configured to support the substrates from below the substrates, the supporting member being capable of vertical movement, wherein the lifter supports the substrates placed at the waiting portion and raises the substrates thereby moving the substrates from the waiting portion to the processing portion, and wherein the lifter supports the substrates placed in the processing portion and lowers the substrates thereby moving the substrates from the processing portion to the waiting portion, and wherein the substrate processing portion is provided with a substrate holding device configured to hold the substrates while the structures are being treated and a first covering member defining at least part of a processing chamber in which the substrate holding device is disposed, and wherein the substrate waiting portion and the substrate lifter are disposed below the substrate holding device, and substrates are transferred between the substrate holding device and a substrate supporting member.
