Background:

Nanoimprint lithography often involves costly and easily damaged stamps.
Developing robust and reusable stamps is crucial for scalable nanofabrication.

Purpose of the Study:

To design and fabricate a reusable diamond stamp for direct preparation of hierarchical nanoarray structures.
To optimize the fabrication process for the diamond stamp, ensuring high-fidelity nanopatterning.
To demonstrate the stamp's effectiveness in creating polymer nanostructures.

Main Methods:

Reactive ion etching using a hierarchical ultrathin alumina membrane (HUTAM) as a mask to create the diamond stamp.
Optimization of etching conditions to achieve vertical nanopores and minimize lateral etching.
Direct stamping of polymer films using the fabricated diamond stamp.

Main Results:

A diamond stamp with a hierarchical pattern was successfully fabricated.
Optimal etching conditions were identified to produce a vertical nanopore structure on the diamond stamp.
A polymer film with a hierarchical nanorod array structure was efficiently prepared using the reusable diamond stamp.
The stamp's super-hardness and smooth surface ensure reusability and avoid the need for release agents.

Conclusions:

The developed diamond stamp offers a cost-effective and durable alternative for nanoimprint lithography.
This method simplifies the fabrication of periodic nanoarray structures, enhancing reproducibility.
The technique holds potential for applications in nanoplasmonics, biochemical sensing, and nanophotonic devices.
