Description
Technical Field

Background
Nanoimprint technology is one method of preparing nanoscale patterns. The method has simple process and low cost, can be used for mass production, and the produced pattern has high resolution. With the development of nanoimprint technology in recent years, nanoimprint methods and nanoimprint apparatuses have been increasingly used. The current embossing methods are mainly hot embossing and UV curing embossing. UV curing embossing is relatively simple due to its operational flow; express developments have been made over the years, and devices and templates for UV curing imprinting have also presented a variety of developments.
The existing UV curing nanoimprint technology mainly comprises rolling imprint and planar imprint: the rolling imprinting is to stack a substrate to be imprinted and a template, then realize bubble removal and compaction structure through rolling pressurization of a roller, and then realize pattern transfer through solidification of a UV (ultraviolet) solidification lamp; still another is to wind the stencil directly onto a roller to effect pattern replication by rolling the roller over the substrate, and then curing with a UV lamp to effect pattern transfer. The planar imprinting directly stacks the substrate and the template, and is cured by a UV lamp after being pressurized by means of vacuumizing, blowing pressurizing or mechanical pressurizing.
The UV curing technology after the substrate and the template are overlapped and rolled for imprinting can realize rapid transfer of patterns, but for large-area pattern copying, because the rolling imprinting roller has a limited disposable contact surface, after the roller rolls over, the stress difference between the front and the back of the roller on the substrate causes the phenomenon of tilting and air inlet at the pressed position of the roller, so that the pattern copying has large-area defects.
The rolling mode of winding the template on the roller, and the bending winding of the template on the roller can cause the microstructure deformation. Resulting in deviations of the reproduced pattern from the original pattern.
Directly superposing the template and the substrate, vacuumizing, pressurizing, and carrying out UV curing imprinting, wherein the problem is not existed for the UV imprinting with a very small area, but when the area needing to be imprinted is enlarged, vacuumizing and pressurizing cannot remove the middle gas, so that the pattern with a large area is lost.
