    摘要: A wet processing apparatus holds on a stage a substrate to be processed and carries out a wet treatment by rotating the stage. The substrate is held by the stage, with the center of the substrate being offset from the rotation center of the stage, using a Bernoulli chuck which causes an inert gas to flow to a back surface of the substrate, so that the substrate is eccentrically rotated along with the rotation of the stage. A first gas supply passage which is used for the Bernoulli chuck is provided at a rotation shaft portion in the stage and the stage is also provided with second gas supply passages which communicate with the first gas supply passage to thereby introduce the inert gas to the back surface of the substrate. The second gas supply passages are axisymmetric with respect to a central axis of the substrate.
