Precision Transmission Electron-Microscopy Sample Preparation Using a Focused Ion-Beam by Extraction Method
A new precision cross-sectional transmission electron microscopy (XTEM) sample preparation method was developed and is reported here. The major advantage of this method over a conventional sample prepared using a focused ion beam (FIB) microsection is that the sample sectioned with a FIB can be extracted directly from the matrix and transferred to a carbon supporting grid for TEM examination. With this technique, a XTEM sample can be prepared, totally eliminating the requirement for mechanical polishing. Samples can be made easily and quickly, thus enhancing both productivity and turnaround time.
