Abstract:
1. A solution processing apparatus, comprising: a processing solution rank to store a processing solution; a holder having an inner space to house a substrate and an opening for the substrate to be in contact with the processing solution; a holder raising and lowering mechanism to raise and lower said holder with respect to said processing solution tank; a substrate raising and lowering mechanism to hold the substrate housed in the inner space of said holder and raise and lower the substrate with respect to the holder; a first electrode which is placed in the inner space of said holder and configured to be in contact with the substrate; a second electrode between which and said first electrode voltage is applied; a pressurizing mechanism to raise pressure in the inner space of said holder; and a controller configured to control said substrate raising and lowering mechanism to raise the substrate with respect to the holder while said pressurizing mechanism raises pressure in the inner space of said holder.
