Abstract

The invention relates to an impressing hard template in a nanostructure, which belongs to the field of nano manufacturing and is characterized in that a porous template with a hard material substrate is prepared by the porous AAO (anodic aluminum oxide) membrane technology and can be directly used as an impressing (from top to bottom) template after the hard substrate is added and the surface modification treatment is carried out. A porous AAO membrane can self-organize and grow into an ordered six-site symmetrical porous structure, and steep holes are uniformly distributed. When the porous AAO membrane is used as the template, various nanostructures and devices with optical, electrical and magnetic properties can be prepared by a processing method of directional assembling from bottom to top such as thermal evaporation, sputtering, deposition and electrochemical assembling. As the hard material substrate is added and the surface modification treatment is carried out, the AAO template technology is transplanted into the field of top-to-bottom surface micro-structure processing. Compared with the present technical method of the common electron beam direct writing, the manufacturing method for the impressing hard template with a nano-grade high-density structure not only has the obvious characteristics of low cost, short period and simple processing, but also can be widely used in the processing as well as researching of the nano-grade high-density surface nanostructure and particularly has broad prospects in the fields of semiconductor lighting and high-density storage. Meanwhile, as the hard substrate is increased, the shortcomings of the present brittle and fragile AAO template are overcome, thereby being more beneficial for duplication of the soft template.

Description

technical field

[0001] The invention relates to a nanostructure embossing hard template, which belongs to the field of nanomanufacturing. Background technique

[0002] With the reduction of chip feature size, traditional optical lithography is facing tremendous pressure from cost and technology, while nanoimprint technology has highlighted its strong competitiveness in the field of nano-processing with its outstanding advantages of low cost, high efficiency, and simplicity. and broad application prospects. Nano-imprint technology uses a template with nano-patterns to press the polymer film on the substrate out of nano-scale patterns, and then performs conventional etching, peeling and other processing on the imprinted parts, and finally makes nano-structures and devices. This technology can Nanostructures are prepared on large-area substrates repeatedly in large batches, and the high-resolution patterns produced have good uniformity and repeatability, are easily compatible ...
