The ideal ion-milled transmission electron microscope (TEM) sample would contain large, thin areas in selected regions, minimal top and bottom surface amorphization, and minimal preferential etching of adjacent materials. This desire has led to studies of these effects and improvements in designs an

โฆ Synopsis
The preparation of TEM cross-section samples from multilayer films or poorly adhering films is discussed in detail in a step-by-step approach designed to enable a competent experimentalist to reproduce the technique. The samples are mounted on an aperture grid and mechanically polished to 2-3 microns in thickness. After ion beam milling for a short period of time (less than 1 hour), a large electron transparent area is obtained. Examples from several thin film systems are discussed.
