ABSTRACT:
Provided is near-field optical probe including: a cantilever arm support portion that is formed of a lower silicon layer of a silicon-on-insulator (SOI) substrate, the cantilever arm support portion having a through hole formed therein at a side of the lower silicon layer; and a cantilever arm forming of a junction oxidation layer pattern and an upper silicon layer pattern on the SOI substrate that are supported on an upper surface of the lower silicon layer and each have a smaller hole than the through hole, a silicon oxidation layer pattern having a tip including an aperture at a vertical end, corresponding with the hole on the upper silicon layer pattern, and an optical transmission prevention layer that is formed on the silicon oxidation layer pattern and does not cover the aperture.
