涉及使用具有能够产生热量的区域的模具的纳米压印平版印刷工艺

Nano impression lithographic process which involves the use of a die having a region able to generate heat
Abstract:
A lithographic process for forming a pattern in relief (20) on a mass (10) of polymeric material comprises the steps of: preparing the mass (10) of polymeric material and a die (12) having a surface region (14) facing towards the mass (10) of polymeric material and which reproduces in negative the pattern in relief (20); heating the die (12) and putting the mass (10) of polymeric material into contact with the die (12) in any temporal sequence, in such a way that the part of the mass (10) of polymeric material in contact with the surface zone (14) is subject to softening; and separating the die (12) from the mass (10) of polymeric material on the surface of which the pattern in relief (20) has been formed. The heating of at least one part of the die (12) is obtained by generation of thermal energy upon dissipation of another form of energy in at least one region (16) of the die (12).
Abstract(Chinese):

用于在聚合物材料（10）上形成浮雕（20）中的图案的平版印刷工艺包括以下步骤：制备聚合物材料块（10）和模具（12），所述模具（12）具有面向 聚合物材料的质量（10）并且以凹凸（20）的形式呈现为负值; 加热模具（12）并将聚合材料的质量块（10）以任何时间顺序与模具（12）接触，使得聚合材料质量（10）的与表面接触的部分 区域（14）容易软化; 以及将模具（12）与形成有凹凸图案（20）的表面上的聚合材料块（10）分离。 模具（12）的至少一部分的加热通过在模具（12）的至少一个区域（16）中消散另一形式的能量时产生热能而获得。
