A substrate treatment device comprises a transporting arm for transporting a substrate within the treatment device, a supporting member, which is disposed on the transporting arm, for supporting the substrate, and a cleaning mechanism, which is installed in the substrate treatment device, for cleaning the supporting member. Since the substrate treatment device is equipped with the cleaning mechanism for cleaning the supporting member, the supporting member can be cleaned as required. Therefore, since the substrate always can be held on a clean supporting member, the particles are prevented from depositing on the rear surface of the substrate.
