Abstract:
1. A method of fabricating a near-field optical probe, comprising: forming a tip having a silicon pattern and an insulating layer covering the outer surface of the silicon pattern on a substrate where a lower silicon layer, an insulating layer, and an upper silicon layer are deposited; implanting ions into an exposed portion of the upper silicon layer; patterning the upper silicon layer to form a cantilever; subsequently removing the lower silicon layer and the insulating layer at the bottom of the substrate corresponding to the tip and the cantilever; and removing the silicon pattern inside the tip to form a near-field optical probe hole in the tip, and wherein, when the silicon pattern inside the tip is removed, the silicon layer into which the ions are implanted is used as an etch stop layer.
