Patent ID: 8353255

Claim:
A device for coating a substrate ( 2 ; 102 ) by spinning-off the coating material, comprising: holding and rotating means for holding and rotating the substrate ( 2 ; 102 ) about an axis (A) essentially perpendicular with respect to the substrate plane; a disk ( 3 ) which is arranged below the substrate ( 2 ; 102 ) and coaxially thereto and which has at least the same diameter as the substrate ( 2 ; 102 ), and distance varying means ( 4 ) for varying the distance (d) between substrate ( 2 ; 102 ) and disk ( 3 ), wherein the disk ( 3 ) has a hole coaxially with respect to the axis (A), and the distance varying means ( 4 ) extends through the hole for supporting the substrate ( 2 , 102 ) and can be elongated or is movable relative to the disk ( 3 ); and wherein the distance varying means ( 4 ) is configured as the holding and rotating means; and wherein the holding and rotating means comprises a centering pin ( 1 ) for engagement with an axial bore of the substrate ( 2 ).
