Abstract:
1. A method of fabricating a semiconductor probe with a high-resolution tip, the method comprising: forming a stripe-shaped mask layer on a top surface of a substrate which is doped with a first impurity; etching the substrate using the mask layer above the substrate as a mask to form a stripe-shaped projection portion on the substrate; doping a region of the substrate, which is not covered by the mask layer, with a second impurity opposite in polarity to the first impurity; forming a stripe-shaped photoresist on the substrate perpendicular to the projection portion; etching the substrate including the projection portion using the photoresist as a mask to form a resistive convex portion with a square pillar shape and first and second electrode regions on the substrate; wherein the first and second electrode regions are formed substantially horizontally, and the resistive convex portion is substantially vertically protruded with respect to the first and second electrode regions; and etching a bottom surface of the substrate to form a cantilever such that the resistive convex portion is located at an end portion of the cantilever.
