Patent ID: 8707890

Claim:
A fluid dispenser to eject fluid onto an area of a lithographic substrate, the dispenser comprising: a substrate table configured to hold a lithographic substrate; and a print head comprising a nozzle arranged to eject an imprintable material onto the lithographic substrate, wherein the print head, the substrate table, or both, are arranged to be moveable relative to the other in first and second opposed substantially parallel directions and the print head is arranged to eject droplets of imprintable material onto the substrate along the first direction and to eject droplets of imprintable material onto the substrate along the second direction on or adjacent the droplets along the first direction, and wherein a speed of the relative movement of the print head, the substrate, or both, in the second direction is substantially equal to a speed of the relative movement of the print head, the substrate, or both, in the first direction.
