Abstract:
1. A resist pattern processing apparatus comprising: a stage for mounting a substrate having a patterned photoresist arranged on a surface thereof; a UV-emitting device for emitting a UV ray to the stage; and an annular member for surrounding an entire periphery of the substrate, the annular member having a thickness and a width selected to ensure a substantially even ozone concentration on a surface of the substrate by sufficiently restraining ozone from diffusing to a periphery of the stage, and being formed from a material that does not transmit ozone therethrough, the material comprising at least one of stainless steel, iron, Cu, Ti, Mo, Cr, Al, and Si, wherein the UV-emitting device comprises a housing having an opening facing the stage, a UV-transmitting member arranged to close the opening, and a UV lamp arranged in a space formed by the housing and the UV-transmitting member, and a gap between the inner peripheral face of the annular member and a side face of the substrate is smaller than the smaller of (1) a thickness of the substrate and (2) a distance between the UV-transmitting member and the substrate.
