发明名称 DEVICE AND METHOD FOR REMOVING LIQUID FROM A SURFACE OF A DISC-LIKE ARTICLE
摘要 A method for removing liquid from a surface of a disc includes, rotating the disc article about an axis perpendicular to the disc's main surface, supplying liquid from a supply port, moved across the substrate towards the edge of the disc, onto the rotated disc, supplying a first gas flow through a first gas supply port onto the disc article to an area whose centre has a distance to the centre of rotational movement of not more than 20 mm, the area being covered with a liquid layer thereby opening the liquid layer at a discrete area, and supplying a second gas flow through a second gas supply port moved across the substrate towards the edge of the substrate onto the rotated disc wherein the distance of the second gas supply port to the centre is lower than the distance of the liquid supply port to the centre.
