Patent ID: 8662879

Claim:
A micro/nano imprint mold of a fabricating process, used to imprint a pattern to a substrate by a material layer, comprising: an upper surface and a lower surface, corresponded to each other; a pre-determined structure, disposed on the lower surface of the mold; and a pressure controlling structure, disposed at the external edge of the upper surface of the mold for increasing the thickness of the external edge of the mold, the thickness of the center portion of the mold being smaller than the peripheral of the mold; wherein, while a pressure is applied to the mold, the pre-determined structure of the mold is pressed onto the substrate so as to form the pattern thereon, the pattern is corresponding to the pre-determined structure and, in the pressing process, the pressure applied to the external edge of the mold is larger than the pressure applied to the center portion of the mold; wherein the pressure controlling structure comprises a plurality of concentric rings.
