Substrate cleaning device and substrate cleaning method |
摘要 |
A substrate cleaning device and a substrate cleaning method reduces liquid drops remaining on a substrate to prevent the irregular heating of the substrate by a heating process due to liquid drops or water marks remaining on the substrate. A cleaning liquid is poured through a cleaning liquid pouring nozzle onto the surface of a substrate such that a region onto which the cleaning liquid is poured moves from a central part toward the circumference of the substrate. A gas is jetted radially outward at a region on the surface of the substrate behind a region onto which the cleaning liquid is poured with respect to the rotating direction of the substrate. The gas forces a liquid film of the cleaning liquid flowing on the surface of the substrate to flow in a circumferential direction and a radially outward direction.
