title: Preparation of cross-sectional transmission electron microscopy samples by electron beam lithography and reactive ion etching.
abstract: A cross-sectional sample preparation technique is described that relies on lithographic and dry-etching processing, thus avoiding metallographic polishing and ion milling. The method is capable of producing cross-sectional transmission electron microscopy samples with a large amount of transparent area (1 micron x 2.5 mm) which allows the examination of many patterned test sites on the same sample from the same chip of a silicon wafer. An example of the application of the technique is given for localized oxidation through a mask.
