In a substrate processing method of processing a substrate in which a processing target layer, an intermediate layer, and a mask layer are stacked one on top of another, the mask layer having an opening that partially exposes the intermediate layer, a thickness of the mask layer is increased by depositing deposits on an upper surface of the mask layer with plasma generated from a mixed gas of SF6 gas and a depositive gas represented in a general equation, CxHyFz (where, x, y, and z are positive integers).
