Patent ID: 7833458

Claim:
An imprinting method comprising: applying a resist to both sides of a substrate; imprinting two stampers comprising protruded patterns against the resist applied to both sides of the substrate; forcing a distal end of a peeling wedge inbetween the substrate and each stamper; and introducing a gas between the substrate and each stamper in order to peel off each stamper from the substrate, wherein a gap between the substrate and each stamper is larger than a thickness of the resist at a position where the distal end of the peeling wedge is forced, the distal end of the peeling wedge is forced into the gap between the substrate and one stamper, in a state that the two stampers are held with vacuum chucks at positions on an inner periphery or an outer periphery of the substrate where no pattern is formed, in order to peel off one stamper, and the distal end of the peeling wedge is forced into the gap between the substrate and the other stamper, in a state that the stamper and the other stamper are held with vacuum chucks, in order to peel off the other stamper.
