Abstract
A nano-imprinting template, a system, and an imprinting method are provided. The nano-imprinting template (10) comprises: a first baseplate (100) transparent to ultraviolet light; an imprinting pattern structure (105) formed on the first surface of the first baseplate (100); a heating element (110) formed on the second surface, opposite to the first surface, of the first baseplate (100), wherein the heating element (110) is transparent to ultraviolet light; and a first electrode pair (115) formed on the second surface and used for supplying a current applied by an external power supply to the heating element (110) so as to make the heating part (110) generate heat. The nano-imprinting template (10) and the system seamlessly integrate an ultraviolet curing nano-imprinting technology with a thermoplastic nano-imprinting technology, which have the advantages of small size of equipment, low cost, simple process and the like. When the template and the system are used to carry out thermoplastic nano-imprinting, a large area of micro-nano patterns can be copied. In addition, when the template and the system are used to carry out UV curing nano-imprinting, the purposes of improving the process throughput and reducing the pattern replication defects are achieved.
