Abstract:
A substrate treating apparatus for treating a substrate in a predetermined substrate treating region, comprising:spin support means for holding and rotating a substrate in a horizontal posture;a holder arm having a treating device attached to a distal end thereof for treating said substrate; andan arm drive mechanism for maintaining said holder arm in a substantially vertical posture at a standby position adjacent to said substrate treating region when said treating device is not in use for substrate treatment, and for turning said holder arm to a substantially horizontal posture to move said treating device to a position for treating said substrate;wherein said arm drive mechanism is operable to maintain said holder arm in said substantially vertical posture in said standby position laterally offset from but adjacent to said substrate treating region when said treating device is not in use, and for turning said holder arm to said substantially horizontal posture, by raising said holder arm from said standby position and tilting said holder arm toward said substrate treating region, to move said treating device to the position for treating said substrate.
