Patent ID: 7279116

Claim:
A method for treating disk-like objects with a first liquid and at least one second liquid at least in a defined edge region of a disk-like object, with the first liquid differing from the second liquid, characterized by the following successive steps: 1.1 the disk-like object is brought close to a mask, with the distance a 1 to the mask being equal to or larger than 0 mm and the mask overlapping with the disk-like object in the region in which the disk-like object is to be treated; 1.2 application of the first liquid, so that the same is held in the region between the mask and the disk-like object; 1.3 increasing the distance between the mask and the disk-like object to a distance a 2 ; 1.4 removal of the residues of the first liquid remaining on the disk-like object; 1.5 reduction of the distance between the mask and the disk-like object to a distance b 1 ; 1.6 application of the second liquid, so that the same is held in the region between the mask and the disk-like object; 1.7 increasing the distance between the mask and the disk-like object to a distance b 2 ; 1.8 removal of the residues of the second liquid remaining on the disk-like object.
