Paper Abstract

A LIGA based tool-set of tips for various scanning probe applications is under investigation by the LSU (mu) SET. This involves fabrication of `micro-columns' using LIGA, followed by an electrochemical sharpening process. Micro-columns ranging from 1.8 micrometers diameter and 14 micrometers tall to 165 micrometers X 165 micrometers and 1000 micrometers tall have been fabricated. In order to understand the sharpening mechanism, commercially available wires with diameters ranging from 25 - 800 micrometers were sharpened. A computer aided design tool, based on deforming finite elements, was developed to simulate the sharpening process.
