Abstract
A method of detaching a film of material (2) from the surface (5) of a substrate (1). An outlet (11) of a fluid delivery device (10) is engaged with an aperture (7, 8) in the substrate (1) from the opposite side of the substrate (1) from the surface (5) to which the film (2) is attached. Fluid is passed out of the outlet (11) and through the aperture (7, 8) to generate a detaching force between the film of material (2) and the surface (5) adjacent to the aperture (7, 8).
