Title: Taper-sectioning techniques in surface analysis
Authors: Brown, Ian K.
Issue Date: 1983
Publisher: © I.K. Brown
Abstract: The provision of accurate composition-depth profiles is important in the investigation and characterization of thin and thick films, surface coatings, surface treatments and many other technological applications. Such profiles are normally obtained using a combination of sputter ion etching and surface analytical techniques. However, there are problems with this approach, particularly at depths greater than 1μm, since surfaces are generally eroded in a non-uniform way. Profiles to these depths are best achieved by using Auger electron spectroscopy in combination with a technique for mechanically tapering the specimen surface. Ball-cratering, which employs a rotating steel ball coated in fine diamond paste to abrade. a well-defined spherical crater in the surface, is shown to be a convenient and accurate method.
