The tapered hole (V) AAO template changes the normal vertical channel AAO template into a structure with large pore size above and small pore size below. The structure is especially suitable for nano surface construction‚ such as nano-imprint lithography. In the release phase of the process‚ V channel has a great advantage over the vertical channel.

1. How to dissolve/etch AAO Template?

There are two methods that we can recommend and please make the best adjustments based on your own experiments.

Slow Removal: Depends on the microstructure evolution, a slow removal of AAO layer might be preferred. This can be achieved by using 5wt% phosphate acid at 30 degrees Celsius. Usually, this process is suitable for single-pass AAO. 

Rapid removal: Use heated 3M NaOH or HCl solution, depending on your specific choice of materials.

2. What's the thickness of the Al substrate?

The Al substrate is 150microns.
