Patent ID: 8113816

Claim:
An imprint device for transferring a finely patterned structure created on a stamper onto a material to be patterned by bringing the stamper and the material to be patterned in contact with each other, the imprint device comprising: a separating unit configured to contact at least one of the stamper and the material to be patterned, and to separate the stamper from the material to be patterned, wherein the separating unit is configured to contact at least one chamfered edge portion, and to separate the stamper from the material to be patterned, said at least one chamfered edge portion being formed on at least one of the stamper and the material to be patterned; and wherein the separating unit includes a plurality of separating pins, wherein each of the separating pins is positioned perpendicular to the stamper, each of the separating pins including a tip which is provided with a separating portion for contacting the chamfered edge portion, said separating unit further including a drive unit configured to drive the separating pins inward and outward in an in-plane direction of the stamper and the material to be patterned to: (1) hold the material to be patterned above and separated from the stamper when the separating pins are driven outward; (2) drop the material to be patterned onto the stamper when the separating pins are driven inward; and (3) bring the separating portions of the tips of the separating pins into contact with the chamfered edge portion when the separating pins are driven outward again, and further configured to drive the separating portions in a layer direction, perpendicular to the in-plane direction, to separate the stamper from the material to be patterned.
