ABSTRACT:
Sharpened microminiature tips are produced by casting in a silicon/silicon dioxide mold. The silicon dioxide layer is formed by exposing cavities in a single crystal substrate to an oxidizing species at a low temperature. Anomalous oxidation of silicon results in a differential thickness in the silicon dioxide layer, providing a convex contour on the surface of the cavities, leading to a sharpened end. The tip can be made from any kind of material that can be cast in a silicon mold. The sharpened tip can be integrated with a member to form a cantilever. An improved scanning probe microscope can be built with the sharpened tip in the cantilever structure.
