Method for preparing invisible anodic aluminum oxide pattern
A method for preparing invisible anodic aluminum oxide (AAO) patterns is revealed. The method includes a plurality of steps. First take an aluminum substrate. Then anodize the aluminum substrate for the first time to get a first anodic aluminum oxide (AAO). Next perform photolithography so that a photoresist forms a pattern on the aluminum substrate with the first AAO. Lastly anodize the aluminum substrate for the second time so that a second AAO is formed on the pattern and the pattern becomes invisible.
