Paper Abstract

The probe forming capability of a microfabricated silicon electrostatic electron lens is under investigation. The lens measures 7 mm by 9 mm by 1.64 mm and consists of three silicon electrodes separated by Pyrex optical fibers. A test structure was designed to house the micromachined lens and a commercially available electron emitter as well as deflectors and an electron detector. Images of a 1000 mesh gold TEM wire grid at a working distance of 4 mm are being obtained at magnifications greater than 10,000 X. Data from the images will be analyzed to estimate the quality of the electron beam.
