Patent ID: 8109751

Claim:
An imprint device for transferring a fine pattern to a material to form a patterned material comprising: a stamper having the fine pattern thereon; and a pressure distribution mechanism, wherein opposed surfaces of the stamper and the material are pressed against one another, and the pressure distribution mechanism comprises a plate provided on a side of one of the stamper and the material opposite to the surface pressed against the other of the material and the stamper, the plate having a curved surface adjacent the one of the stamper and the material, and a buffer layer provided on and conforming to the curved surface such that the buffer layer has a curved surface corresponding to the curved surface of the plate, the buffer layer having a lower coefficient of elasticity than that of the plate, the stamper or the material, and having a thickness greater than a difference between a maximum thickness of the curved surface of the plate and a minimum thickness of the curved surface of the plate in an area of the plate having a diameter corresponding to a diameter of the material.
