Abstract:
1. A method of manufacturing a near-field optical probe, the method comprising: forming a junction oxidation layer pattern having a first hole on a lower silicon layer; forming a SOI substrate by forming an upper silicon layer on the junction oxidation layer pattern which includes the first hole; forming a tip structure on the upper silicon layer formed over the first hole; sequentially forming a silicon oxidation layer pattern and an upper silicon layer pattern that form a cantilever arm on the outer surface of the tip structure and the upper silicon layer; forming an etching mask layer pattern on a rear surface of the lower silicon layer for forming a cantilever arm support portion; forming a through hole exposing the junction oxidation layer pattern and a tip having an aperture above a second hole that is smaller than the through hole by etching the lower silicon layer and the upper silicon layer pattern in the tip structure on the first hole using the etching mask layer pattern as an etching mask; and forming an optical transmission prevention layer on the silicon oxidation layer pattern that does not cover the aperture, wherein the cantilever arm is formed of the upper silicon layer pattern and the junction oxidation layer pattern that are supported on an upper surface of the lower silicon layer and each have the second hole that is smaller than the through hole, of the silicon oxidation layer pattern including the tip having the aperture corresponding to the second hole, and of the optical transmission prevention layer.
